Last time, I have shared squaring numbers ending in 5. This time let us try to square numbers near 100 - those numbers less than 100 or numbers greater than 100.

**Number near and less than 100.**

*Find the square of 98.*

**Example 1:**s

*tep 1*. Find the difference of 100 and the number. That is 100 - 98 = 2.

s

*tep 2*. Since the number is less than 100, subtract 2 from the given number.

s

*tep 3*. Square the result in step 1. The square of 2 is 4. s

*tep 4*. Combine the result in step 2 and 3. The first two digits from the left will be from the result in step 2 and the other two digits will be from the result in step 3.

Since the result in step 3 is only a one digit number, we need to add 0 to make it a

two digit number. The result which is 4 becomes 04.

Therefore the square of 98 is 9,604.

**: Find the square of 91.**

*Example 2**step 1*. Find the difference of 100 and the given number. That is 100 - 91 = 9.

*step 2.*Subtract 9 from the given number. That is 91 - 9 = 82.

*step 3.*Square the result in step 1. That is the square of 9 which is 81.

*step 4.*Combine the results in step 2 and 3. The result is 8281.

*Therefore, the square of 91 is 8,281.*

Try to find the square of the following numbers:

1. 93

2. 94

3. 96

4. 97

5. 99
