One of the easiest method to find square of any number is

Step 1: Identify the number whose square we need to find.

Step 2: Find the difference between the identified number and its nearest 10s number.

Step 3: Add and subtract the answer of Step 2 to the number identified in Step 1. We obtain 2 results in this step.

Step 4: Multiply the two numbers obtained in Step 3

Step 5: Square the result obtained in Step 2.

Step 6: Add the result of Step 5 to the result of Step 4 to get the final answer.Now, that we have detailed the steps of the trick, we should try using it to find squares of some numbers. Let us find the square of number 25

Step 1: Identify the number whose square we need to find.

25

Step 2: Find the difference between the identified number and its nearest 10s number.

The nearest 10s number to 25 is 30 and the difference between them is 5

Step 3:Add and subtract the answer of Step 2 to the number identified in Step 1.

25+5=30

25-5=20

Step 4:Multiply the two numbers obtained in Step 3.

30×20=600

Step 5: Square the result obtained in Step 2.

5²=25

Step 6: Add the result of Step 5 to the result of Step 4 to get the final answer.

600+25

Here is the final answer. The square of 25 is 625.
