Yea it still can work. However there are combinations that will give you 9 instead of 18. For example if the put in 054 it will just input as 54. If then say revers the digits and subtract they will do 54-45=9. There are people who will do weird things. You can definitely not include that instruction about 0 and risk getting 9 as it is super rare.
@@LearnYourMagicPerhaps it depends on the calculator. I used the 054 example in your reply on two different devices and it still gives the desired force number when reversed and subtracted. I haven't had any issues ever when performing. 9 will be the result if 054 is reversed and then accidentally added instead, because the final three digits will be 504
Typo on your thumbnail. PEDICTION is missing the R. 291 - 192 = 99. That's not a 3 digit number. But 9 + 9 = 18, so it still works. Any 3 digits, say X, Y, and Z. If the difference between X and Z is 1, then it'll be a 2 digit number. So (X)(Y)(Z) becomes (X)(Y)(X-1) or (X)(Y)(X+1). Then subtracting, (X)(Y)(X +/- 1) - (X +/- 1)(Y)(X) = (-/+ 1)(0)(+/- 1). If the ones digit is -1, then it borrows from the tens column. Since the tens column is 0, it has to borrow from the hundreds column. Thus, if the X and Z (hundreds and ones) columns differ by 1, this will lead to a two digit number. If the ones digit is +1, then the final answer is still going to be 99, but -99.
I think that's where the "is your number less than 52?" question comes in handy. if they say no, you can just tell them to add the digits together and still get to 18
Excellent! 👍👍
I have gone through this force with 3 different digits while also using 0 & it still seems to work and add up to 18. Any combo with 0 that wouldn't?
