Represent the number as: 1*X + 10*Y + 100*Z. The inverse would be: 1*Z + 10*Y + 100*X. Subtract the inverse and get: 99*Z - 99*X. Also can be written as: 99*(Z-X). Lets replace (Z-X) with N: 99*N. Lets rewrite as: 100*N - N. Lets rewrite as 100*(N-1) + 100 - N. Lets rewrite as 100*(N-1) + 90 + (10-N). Thus the inverse is: 100*(10-N) + 90 + (N-1).

453 - 354 = 99 to in some cases where there is a difference of 1 between first and last digit you would have to add 0 to the first result to get 1089 but it will still work just add extra step by saying: " Add 0 in the end if you got a two digit result".
the number only needs to be not symmetrical. Two of the same are fine as long as they are something like 221 oder 667. Only problem is something like 121 or 444. edit: even 998 is fine as long you treat the result of { 998 - 899 = 99 } as a three digit number of 099. 099 + 990 = 1089
Also if you do the first part where the subtraction happens, you can predict the result of the operation if you know the first or last digit of it. middle digit is always 9 and the sum of the other two digits is always 9. So in the example of the video we have 495, knowing 5 you can find 4 and construct 495. People will be surprised. The only case where this doesn't work is with 3 digit numbers where all digits are the same (eg 444, 888 etc)
Here's why it happens: 1. **Three-Digit Number**: Consider any three-digit number where the first and last digits differ by at least two. Let's call it ABC, where A, B, and C are its digits. 2. **Reversing and Subtracting**: When you reverse this number, you get CBA. Subtracting CBA from ABC (assuming A is greater than C) gives a new number. This subtraction aligns with the form (100A + 10B + C) - (100C + 10B + A) = 99A - 99C. 3. **Result of Subtraction**: Simplifying 99A - 99C, you get 99(A - C). Since A and C are at least two digits apart, the minimum value for (A - C) is 2 (e.g., if A is 3 and C is 1), and the maximum is 9 (e.g., if A is 9 and C is 0). This results in a number that is two digits long, and its first digit is always 9. 4. **Intermediate Number Characteristics**: The intermediate number (after subtraction but before adding the reverse) is always of the form 9X9, where X is a digit. This is because the hundreds and units place will always be 9 due to the subtraction process described above. 5. **Reversing the Intermediate Number**: When you reverse this number, it becomes 9X9 again, as reversing doesn't change the position of the digits due to its symmetry. 6. **Final Sum**: Adding the intermediate number and its reverse, both being 9X9, will always lead to 1089. This is because 900 + 90 + 9 equals 999, and adding it to another 999 (since the reverse is the same) results in 1089. In summary, the specific properties of base-10 subtraction and the constraints placed on the original number (three digits, first and last digits differ by at least two) ensure that this trick works, leading to the consistent result of 1089.
That's so awesome..thank you....unless it's not. Ramanujam taxi number(story) is 1729 which is the smallest number which can be expressed as the sum of two different cubes in two different ways.
When I was 8 I discovered that you can take any number larger than 9 and up to infinity and subtract its opposite and that number is ALWAYS perfectly divisible by 9, or 3 because 3 squared is obviously 9
The claim should be that the difference of any number (greater than 9 and not equal to its mirrored version) and its mirrored version, is always divisible by 9. Essentially, it all comes down to this: If a>0; x, y ≥ 0; x>y and a, x, y are all integers: D = a * (10 ^ x) - a * (10 ^ y) = = a * ((10 ^ x) - (10 ^ y)) = a * M D is divisible by 9 if M is also divisible by 9. M is always divisible by 9 for the same reason the differences 1000-10=990 and 100-1=99 are all divisible by 9.

*Let three digit number:* xyz= 100x +10y+ z *Reverse:* zyx = 100z + 10y + x *Subtract:* xyz-zyx = a9b After subtraction, the result is a9b.. where Middle digit is always 9 and sum of a and b is always 9. *Reverse again:* b9a *Add:* a9b + b9a = (a+b)/18/(a+b) We know a+b = 9 Let's put the values: 9/18/9.. Carry 1 of 18 to hundredth place, so it becomes 10/8/9.. i.e. 1089. No it's not magic.. simple maths...
Let the unique digits of the number be *x* , *y* , *z* in order. So the number is: *100x + 10y + z* And the reverse of it is: *100z + 10y + x* Subtracting the reverse from original gives: *99(x-z)* If *x>z* let *t=x-z* , else let *t=z-x* So the number we have, ignoring the sign, is: *99(t) = 100(t) - t* *= 100(t-1+1) - t* *= 100(t-1) + 100 - t* *= 100(t-1) + 10(9) +(10 - t)* Possible values of *t* : 1 to 9 *(t-1)* : 0 to 8 *(10 - t)* : 1 to 9 so they are single digits. So the number we have is: *100(p) + 10(9) + q* where *p = (t-1)* *q = (10-t)* The reverse of this number is: *100q + 10(9) + p* Adding these together, we have: *101(p + q) + 180* *= 101(t-1 + 10-t) + 180* *= 101(9) + 180* *= 1089*
3 different numbers even don't need. You can assume atleast 2 same numbers either on left side of 3 digit set or at right side of them, for example 221 or 122 or 488 or 884. These sets of numbers also work.
The phenomenon you're describing with the number 1089 is a well-known mathematical trick. It works with most three-digit numbers, as long as the first and last digits differ by at least two. Here's how it works: Choose any three-digit number where the digits are not all the same (like 651). Reverse the digits to form a new number (156 from 651). Subtract the smaller number from the larger number (651 - 156 = 495). Reverse the digits of this result (594 from 495). Add this number to the original difference (495 + 594). The final result is almost always 1089. This trick works because of the properties of number manipulation and digit rearrangement
When I first heard this, I was told no repeat numbers. But it doesn't work if you say: 132 or 796 , 495, 738, etc. If the 1st and 3rd numbers are sequential, the inverce makes 99.
You can't just ignore the minus of a negative number. you have to flip it (hit +/- button). if you add to a negative number it's not going to work. OR you can make the trick look more impressive and (seemingly unpredictable) by asking them if the number is positive or negative. If it is positive, add, if negative, subtract.
If they get a negative number after the first step, ignoring it is a bad idea, because if they don't clear it out and re-type it correctly as a positive number, this will not work.
Look it in this way... Take any 3 digit number and calculate it's difference from it's opposite number. Use word difference. Difference of any two numbers is considered positive.
No need to clear it out. Simply multiply by "-1", OR subtract its reverse instead of adding it, OR click on the change sign (+/-) function (if one is available).
To everyone! Every 3 different digits works if it's done in the right way! 🙃 Edit To replies:- I can't calculate every number so here are the two common mistakes- 1) Listen carefully in the video if you get an answer in negative ➖ remove that and make it positive! 2) If you get an answer as a two digit number (most commonly 99) add 0 before the number so 99 becomes 099 then add 099+990 = 1089 🤓
If we take 897 and subtract it by reversing the number which is 797 so it will be 897 -798 =99 So after that we will add it by reversing the number but here the two digits of the number is the same so it will be 99 + 99 =189 It happen with many number still some number have a different result . There are many number that have a different result like 291 , 136 , 102, 594 .
You can technically do it with larger than 3 digit numbers, but you need to start adding in a decimal place to make it equal 1089. Otherwise you start getting things like 108090.
@@USE_YOUR_BRAIN So, I realize it's not how you would probably normally treat a decimal. But yeah, if you use ###.# instead of ####, it will work. Last I tried at least.
I have written a program to check all the 3 digits numbers. Only 640 have 1089 answers. The rest is incorrect because it will encounter a palindrome during the process.
You last digit should be lower than first digit for this to work. Best case , ask for number in decreasing order. It only works if number is in decreasing order. Like 652, 873 , 892, 583 etc
She said to ignore the negative so it doesn't matter which of the two digits is larger. It only doesn't work when the first and last digits are the same
@@mayankbaber9384Never Proposed it, Most People really don't appreciate his far more superior work in Advanced Number Theory as much as Trivial Results in ordinary Arithmetic which they claim he discovered it(It's the case of Cultural Superiority).
Below is a very very long and rather convoluted mathematical explanation of this problem. Let the first digit of the first number be a, second digit be b and third digit be c. Then, first number = 100a + 10b + c Reverse of this number= 100c + 10b + a First number - its reverse = 100a + 10b + c - (100c + 10b + a) = 99a - 99c = 99 (a - c) The next set of calculations is to find the 3-digit formula of the above number. = 99 (a - c - 1) + 99 = 100 (a - c - 1) - a + c + 1 + 90 + 9 = 100 ((a - c) - 1) + 90 + (10 - (a - c)) Thus, we have the first digit of the difference as (a - c) - 1, second digit as 9, and third digit as 10 - (a - c). The reverse of the above number is = 100 (10 - (a - c)) + 90 + ((a - c) - 1) Sum of the above 2 numbers = 100 ((a - c) - 1) + 90 + (10 - (a - c)) + 100 (10 - (a - c)) + 90 + ((a - c) - 1) = 100(a - c) - 100 + 90 + 10 - (a - c) + 1000 - 100(a - c) + 90 + (a - c) - 1 = 1000 + 90 - 1 = 1089 One peculiar scenario where this rule might fail is when the difference of the first number and its reverse is 99. E.g. 201 - 102 = 99 In this case, 99 + 99 = 198 which is not equal to 1089. However if we consider 99 as a 3-digit number, that is 099, then we have 099 + 990 = 1089.

@@usernameusernamwell it works for the numbers you mentioned. It is just that you ignore the negative sign if the difference is negative and if the difference comes out as a 2 digit number you should consider it as 3 digits with 100's place being "0" and proceed. For example for 102 102-201=-99 Ignore the -ve sign and consider it as 099 099+990=1089

Represent the number as: 1*X + 10*Y + 100*Z.
The inverse would be: 1*Z + 10*Y + 100*X.
Subtract the inverse and get: 99*Z - 99*X.
Also can be written as: 99*(Z-X).
Lets replace (Z-X) with N: 99*N.
Lets rewrite as: 100*N - N.
Lets rewrite as 100*(N-1) + 100 - N.
Lets rewrite as 100*(N-1) + 90 + (10-N).
Thus the inverse is: 100*(10-N) + 90 + (N-1).
Add these together and we get: 99*N + 1000 - 100*N + 90 + N - 1.
Squish together and get: 1000 + 90 - 1 = 1089

If abc is the 3 different digit number we can write it algebraically as 100a+10b+c
Then the reverse digit number will be 100c+10b+a
Now subtract the reverse digit number from original one
(100a+10b+c)-(100c+10b+a)
The new number will be
(100-1)a+(10-10)b+(1-100)c
Or
99a-99c
Or *99(a-c)* ..... (1)
Since a and c are single digit numbers i.e
a, b belongs [0,1,2,3,4,5,6,7,8,9]
So (a-c) will also be a single digit number.
[But a≠0 because abc is a 3 digit number]
Henc (a-c) belongs to [1,2,3,4,5,6,7,8,9]
_We excluded 0 because
a-c=0 if and only if a=c
And we know that a,b and c are three different digits. a≠c
Now lets substitute the other possible values of (a-c) one by one
For *a-c=1*
(1)=> 99×1=99
Now add reverse
99+99=198
Add reverse digit number again
198+891=1089
For *a-c=2*
(1)=> 99×2=198
Now add reversed digits
198+891=1089
For *a-c=3*
(1)=> 99×3=297
Now add reversed digits
297+792=1089
For *a-c=4*
(1)=> 99×4=396
Now add reversed digits
396+693=1089
For *a-c=5*
(1)=> 99×5=495
Now add reversed digits
495+594=1089
For *a-c=6*
(1)=> 99×6=594
Now add reversed digits
594+495=1089
For *a-c=7*
(1)=> 99×7=693
Now add reversed digits
693+396=1089
For *a-c=8*
(1)=> 99×8=792
Now add reversed digits
792+297=1089
For *a-c=9*
(1)=> 99×9=891
Now add reversed digits
891+198=1089
Similarly for negative values of (a-c)
Ignore the negative we will conclude with the same answers.

453 - 354 = 99 to in some cases where there is a difference of 1 between first and last digit you would have to add 0 to the first result to get 1089 but it will still work just add extra step by saying: " Add 0 in the end if you got a two digit result".
99 in the same as 099. Also this works with as many digits. With 4 digits it’s 10,989. And so on

Also if you do the first part where the subtraction happens, you can predict the result of the operation if you know the first or last digit of it. middle digit is always 9 and the sum of the other two digits is always 9. So in the example of the video we have 495, knowing 5 you can find 4 and construct 495. People will be surprised. The only case where this doesn't work is with 3 digit numbers where all digits are the same (eg 444, 888 etc)
Here's why it happens:
1. **Three-Digit Number**: Consider any three-digit number where the first and last digits differ by at least two. Let's call it ABC, where A, B, and C are its digits.
2. **Reversing and Subtracting**: When you reverse this number, you get CBA. Subtracting CBA from ABC (assuming A is greater than C) gives a new number. This subtraction aligns with the form (100A + 10B + C) - (100C + 10B + A) = 99A - 99C.
3. **Result of Subtraction**: Simplifying 99A - 99C, you get 99(A - C). Since A and C are at least two digits apart, the minimum value for (A - C) is 2 (e.g., if A is 3 and C is 1), and the maximum is 9 (e.g., if A is 9 and C is 0). This results in a number that is two digits long, and its first digit is always 9.
4. **Intermediate Number Characteristics**: The intermediate number (after subtraction but before adding the reverse) is always of the form 9X9, where X is a digit. This is because the hundreds and units place will always be 9 due to the subtraction process described above.
5. **Reversing the Intermediate Number**: When you reverse this number, it becomes 9X9 again, as reversing doesn't change the position of the digits due to its symmetry.
6. **Final Sum**: Adding the intermediate number and its reverse, both being 9X9, will always lead to 1089. This is because 900 + 90 + 9 equals 999, and adding it to another 999 (since the reverse is the same) results in 1089.
In summary, the specific properties of base-10 subtraction and the constraints placed on the original number (three digits, first and last digits differ by at least two) ensure that this trick works, leading to the consistent result of 1089.

The claim should be that the difference of any number (greater than 9 and not equal to its mirrored version) and its mirrored version, is always divisible by 9. Essentially, it all comes down to this:
If a>0; x, y ≥ 0; x>y and a, x, y are all integers:
D = a * (10 ^ x) - a * (10 ^ y) =
= a * ((10 ^ x) - (10 ^ y)) = a * M
D is divisible by 9 if M is also divisible by 9.
M is always divisible by 9 for the same
reason the differences 1000-10=990 and 100-1=99 are all divisible by 9.

Real magic is in your eyes beautiful❤
Let the unique digits of the number be *x* , *y* , *z* in order.
So the number is:
*100x + 10y + z*
And the reverse of it is:
*100z + 10y + x*
Subtracting the reverse from original gives:
*99(x-z)*
If *x>z* let *t=x-z* ,
else let *t=z-x*
So the number we have, ignoring the sign, is:
*99(t) = 100(t) - t*
*= 100(t-1+1) - t*
*= 100(t-1) + 100 - t*
*= 100(t-1) + 10(9) +(10 - t)*
Possible values of
*t* : 1 to 9
*(t-1)* : 0 to 8
*(10 - t)* : 1 to 9
so they are single digits.
So the number we have is:
*100(p) + 10(9) + q*
where
*p = (t-1)*
*q = (10-t)*
The reverse of this number is:
*100q + 10(9) + p*
Adding these together, we have:
*101(p + q) + 180*
*= 101(t-1 + 10-t) + 180*
*= 101(9) + 180*
*= 1089*

3 different numbers even don't need. You can assume atleast 2 same numbers either on left side of 3 digit set or at right side of them, for example 221 or 122 or 488 or 884. These sets of numbers also work.
The new definition of beauty.
The phenomenon you're describing with the number 1089 is a well-known mathematical trick. It works with most three-digit numbers, as long as the first and last digits differ by at least two. Here's how it works:
Choose any three-digit number where the digits are not all the same (like 651).
Reverse the digits to form a new number (156 from 651).
Subtract the smaller number from the larger number (651 - 156 = 495).
Reverse the digits of this result (594 from 495).
Add this number to the original difference (495 + 594).
The final result is almost always 1089. This trick works because of the properties of number manipulation and digit rearrangement

You can't just ignore the minus of a negative number. you have to flip it (hit +/- button). if you add to a negative number it's not going to work. OR you can make the trick look more impressive and (seemingly unpredictable) by asking them if the number is positive or negative. If it is positive, add, if negative, subtract.

Wow her children gonna be magicians and mathematicians!!
Below is a very very long and rather convoluted mathematical explanation of this problem.
Let the first digit of the first number be a, second digit be b and third digit be c.
Then, first number = 100a + 10b + c
Reverse of this number= 100c + 10b + a
First number - its reverse
= 100a + 10b + c - (100c + 10b + a)
= 99a - 99c
= 99 (a - c)
The next set of calculations is to find the 3-digit formula of the above number.
= 99 (a - c - 1) + 99
= 100 (a - c - 1) - a + c + 1 + 90 + 9
= 100 ((a - c) - 1) + 90 + (10 - (a - c))
Thus, we have the first digit of the difference as (a - c) - 1, second digit as 9, and third digit as 10 - (a - c).
The reverse of the above number is =
100 (10 - (a - c)) + 90 + ((a - c) - 1)
Sum of the above 2 numbers
= 100 ((a - c) - 1) + 90 + (10 - (a - c))
+ 100 (10 - (a - c)) + 90 + ((a - c) - 1)
= 100(a - c) - 100 + 90 + 10 - (a - c) + 1000 - 100(a - c) + 90 + (a - c) - 1
= 1000 + 90 - 1
= 1089
One peculiar scenario where this rule might fail is when the difference of the first number and its reverse is 99.
E.g. 201 - 102 = 99
In this case, 99 + 99 = 198 which is not equal to 1089.
However if we consider 99 as a 3-digit number, that is 099, then we have 099 + 990 = 1089.
Yes, you have to assign zero value to the hundreds column before reversing it.
