Squaring number ending in five : Vedic Maths Trick

This is the most common, yet very interesting trick of Vedic Maths. Using this technique you can find the square of any number ending in 5 very easily. Given below is the step by step explanation of this Vedic Maths Method

Let us take a 2 digit number,

Say the number is a5 (=10a+5), where is the digit in ten's place

Square of a5= a x (a+1) | 25

For example,

45² = (40 + 5) ², It is of the form (10a+b)² for a = 4

Giving the answer a (a+1) | 25 ( | stands for concatenation}

i.e. 4 x (4+1) | 25 = 4 x 5 | 25 = 2025

Similarly we can proceed for 3 digit numbers ending in 5

Few more examples:

95²= 9 x 10 | 25 = 9025

125² = 12 x 13 | 25 = 15625

505² = 50 x 51 | 25 = 255025
