The Addition Formula

The basic formula for addition is simple: you add two or more numbers together to get their sum. Mathematically, this is represented as:

Addition Formula

Sum = Number₁ + Number₂ + Number₃ + ... + Numberₙ

Where:

  • Sum is the total of all numbers added together
  • Number₁, Number₂, etc. are the individual numbers being added
  • n is the total count of numbers being added

This formula works for any set of numbers, whether they are whole numbers, decimals, or even negative numbers.

Worked Examples

Let's look at a few examples to see how addition works in practice.

Example 1: Adding Whole Numbers

Calculate the sum of 5, 12, and 8.

Calculation

5 + 12 + 8 = 25

First, add 5 and 12 to get 17. Then add 8 to get the final sum of 25.

Example 2: Adding Decimals

Calculate the sum of 3.5, 2.75, and 1.25.

Calculation

3.5 + 2.75 + 1.25 = 7.50

First, add 3.5 and 2.75 to get 6.25. Then add 1.25 to get the final sum of 7.50.

Example 3: Adding Negative Numbers

Calculate the sum of -4, 7, and -2.

Calculation

-4 + 7 + (-2) = 1

First, add -4 and 7 to get 3. Then add -2 to get the final sum of 1.
