Square numbers in 1 second🔢

Ok now do that with anything that doesn’t end with a 5

Only works for numbers ending in 5 So, this is not helpful, mostly misleading

She cannot explain why it is so😂 Any two digits number X5 = 10 * X + 5. X5 *X5 = (10 * X + 5) * (10*X + 5) =100X *X + 100X +25=100X *(X+1) + 25= X(X+1) *100 +25😎

Helpful tip ❤️

I think it works only for domestic numbers ending with 5

Why on the earth do we need the square of 75? 105? Even though if we need, what is calculator for?

9025

34^2 = 1216 😀😀😀
