**Example 1:**

103 x 103 = 10609

**Steps:**

Find the difference between 100 and the number. 103 - 100 = 3

- 103 + 3 = 106(00) <- Add the difference from the number being squared.
- 3 x 3 = 9 <- Square the difference.
- 10600 + 9 = 10609.

**Example 2:**

112 x 112 = 12544

**Steps:**

Find the difference between 100 and the number. 112 - 100 = 12

- 112 + 12 = 124(00) <- Add the difference from the number being squared.
- 12 x 12 = 144 <- Square the difference.
- 12400 + 144 = 12544.
