Addition and Subtraction Formulas With Example

Addition Formula:

The addition formula is quite straightforward. You simply add two or more numbers together to get the sum.

Example 1: 5 + 3 = 8

Example 2: 12 + 7 = 19

Example 3: 25 + 14 = 39

Example 4: 100 + 50 = 150

Example 5: 3.5 + 2.5 = 6.0

Subtraction Formula:

The Subtraction formula is used to find the difference between two numbers. You subtract the second number from the first.

Example 6: 10 – 4 = 6

Example 7: 15 – 8 = 7

Example 8: 50 – 22 = 28
