We have already learned how to **square numbers from 80 to 100**. In this post, we are going to show a shortcut on squaring numbers from 50 to 70. Here are example and the steps.

**Example 1: **52^{2}

Step 1: Consider how far is 52 from 50. The answer is 2.

Step 2: Add 2 to 25. This gives us 27, 2 is the thousands and 7 the hundreds digit. This gives us 27xx where xx are the tens and ones digits.

Note: The number 25 comes from squaring the tens digit which is 5. I will explain this in the next post.

Step 3: To get xx, we square the ones digit of the given which is 2. This gives us 4. Since we only have 1 digit, we put 0 before 4, giving the value of xx as 04.

Therefore, 52^{2}= 2704 Continue reading
