Adding Integers Practice 1: Find the sum of each expression. Click the button below to try all our FREE PDF printable pre-algebra worksheets.

Integers are always whole numbers. They can be either positive or negative. There are some rules that you have to follow in order to add and subtract expressions with positive and negative integers.

### Adding integers with the same sign

If the signs of the integers match, we will add the given integers together and keep the sum with the same sign.

Example: 5 + 6 = 11

Example: (-5) + (-6) = -11

### Adding integers with different signs

If you have to add one positive and one negative number, or two integers with different signs that don’t match, you have to subtract the integers as if they were all positive and keep the answer with the larger integer’s sign.

Example: 5 + (-6) = -1

Example: (-5) + 6 = 1

Although, this worksheet is to add integers, let’s also learn how to subtract integers with the same and different signs.

### Subtracting integers with the same sign

This is similar to adding integers with different signs. If the signs of the integers match, we will have to subtract the smaller integer from the larger integer and keep the difference with the larger integer’s sign.

Example: 5 – 6 = -1

Example: (-5) – (-6) = 1

### Subtracting integers with different signs

This is similar to adding integers with the same sign.

Example: 5 – (-6) = 11

Example: (-5) – 6 = -11
