## Step by step guide to add and subtract integers

- Integers include: zero, counting numbers, and the negative of the counting numbers. \(\{… , – \ 3, – \ 2, – \ 1, 0, 1, 2, 3 , …\} \)
- Add a positive integer by moving to the right on the number line.
- Add a negative integer by moving to the left on the number line.
- Subtract an integer by adding its opposite.

### Adding and Subtracting Integers – Example 1:

Solve**.** \( (- \ 2) \ – \ (- \ 6)=\)

**Solution:**

Keep the first number, and convert the sign of the second number to it’s opposite. (change subtraction into addition. Then: \((- \ 2) \ \color{blue}{+} \ 6=4\)

### Adding and Subtracting Integers – Example 2:

Solve**.** \( 8 \ + \ (12 \ – \ 20)=\)

**Solution:**

First subtract the numbers in brackets, \(12 \ – \ 20= \ – \ 8\)

Then: \(8 \ + \ (- \ 8)= \ → \) change addition into subtraction: \(8 \ \color{blue}{-} \ 8=0\)

### Adding and Subtracting Integers – Example 3:

Solve. \((-8)-(-5)=\)

**Solution:**

Keep the first number and convert the sign of the second number to it’s opposite. (change subtraction into addition. Then: \((-8)+5= \ -3\)

### Adding and Subtracting Integers – Example 4:

Solve. \(10+(4-8)=\)

**Solution:**

First subtract the numbers in brackets, \(4-8= \ -4\)

Then: \(10+(-4)= →\) change addition into subtraction: \(10-4=6\)
