Question

How do i find 20×50 using mental math

Answer 1

What you can do is see it like this 20x50 or take 5x2 which is 10 and then count how many zeroz there are in the original equation and add them. Since there are 2 zeros you add them to the 10, so the answer will be 1000.

Answer 2

2 times 5 = 10 then u add the two 0s back to get 1,000
