How to Calculate Faster than a Calculator - Mental Math #1

[@thakurfamily9669]

0:13 you're right. Found it in 6 secs 💀

[@Micro_Dust]

Just some simple proofs:
Trick 2:
(10x+5)*(10x+5) = 100x*x + 100x + 25 = (x*x + x)*100 + 25 = (x)*(x+1)*100 + 25
e.g. 85*85 = (8)*(8+1)*100 + 25 = 7225
Trick 3:
let y

[@BRUNOHENRIQUE-fk6jt]

(3:33) 9025 is the answer

[@raghvendrasingh1289]

11^2 =121
111^2 = 12321
1111^2 = 1234321
11111^2 = 123454321
multiplying by 99
56×99 = 5544
73×99 = 7227
rule , 56 - 1 = 55 , 99 - 55 = 44
multiplying by 999
234×999 = 233766
84×999 = 83916
rule, 234 - 1 = 233 , 999 - 233 = 766

Multiplying two digit number with same first digit and ending with 5 ✅

89*81 = (8*9)(9*1) = 7209
Amazing video sir! ❤ Waiting for part-2

[@brain_station_videos]

Thanks, I'm glad you liked it! Part 2 is coming soon! (but you know only if this video gets 10k likes)

[@MR_football27]

Amazing really need a part 2 ❤❤

[@thecricketmerchant]

89x81=
8x9 = 72
9x1=9
There you go its 7209

[@tastyfood2020]

Bro i can't wait to learn part 2 please post it quick

[@tvrashid]

I know the trick
83x87 = 85²-2²
85²=6400+800+25 = 7225
85²-2² = 7221

[@lewisgilliland60]

Last one… 7209👌

[@flashwebby]

Can't wait for part 2

[@iexistalso]

95*95=9025
89*81=7201❤

[@Psst65]

3:56 4+3= 12, not seven.
Edit: I meant multiplication

[@brain_station_videos]

🥲 tell me you are high without telling me you are high

[@Psst65]

@@brain_station_videosoops I meant multiplication, I though you were trying to implement that we multiply

[@Psst65]

@@brain_station_videos it’s a typo I meant to put a multiplication sign, not an addition sign.

[@ArghaBanerjee-q9c]

95*95 is 9025. The calculation is 9*10 & 5*5 i.e. 90 & 25 which is 9025. ❤❤

Could the thumbnail be accurate?

[@bossofdarkness0528]

Yes if you practiced enough

@@MD-kv9zo ah alright, I don't mind it.

[@some_memory1]

Good series

[@DanCarloDioquino]

Oh I remembered something
Ex 83 × 87 = 7221
Explanation
If last digit adds up to ten just multiply em
Then n(n+1) where n is the tenth digit
8(8+1)=8(9)=72
4(7)=21
=7221
Dunno if u get it I just saw this a year ago

[@rmadhavan7308]

can you explain things like calculus and etc. in layman’s language??

[@talonwilliam2295]

3:36 9025

[@thecricketmerchant]

95x95 = 9x10 or 90
Then add 25 to it
9025 is your answer

This trick only work for a few numbers

[@faladodososomeme6739]

Yeah that’s the whole point tho. It works in numbers that add to 10, both 5s or times 11
