Vedic Mathematics for finding square of a number whose unit place carries 5

As we learned from my previous lesson

i,e;  (In case of two 2-digited numbers whose digits in 10's place are same and sum of the digits in unit places is 10

For example:- 38 and 32 (10's place digits are equal and 8+2=10)

38×32 can be found very easily

3×(3+1)×100=1200 (the number in 10's place × next number tio it ×100

8×2  =16  (product of digits in unit places)

add the result and get the product

38×32=1200+25=1225

That's the result.

We can apply it to find square of numbers ending with digit 5

35×35 = (3×4×100)+(5×5) =1225

So, square of 35=1225

Practice more

square of 85= 8×9×100+ 5×5 = 7200+25 =7225

Is it not interesting?
