## Integer Word Problems: Addition and Subtraction

Although integers can be really tricky, integer word problems seem a bit easier, because they really highlight the fact that adding and subtracting integers is just adding and subtracting, sometimes with a twist.

## Multiply and Divide Integers

Adding and multiplying integers includes multiplying and dividing positive whole numbers, as well as multiplying and dividing negative numbers.

All of the normal rules of multiplication and division apply. And these problems are all much easier if you know your multiplication and division facts.

The only complication when you work with integers is remembering how positive and negative numbers work with each other.

## Adding and Subtracting Integers (Positive and Negative Numbers)

Adding and subtracting integers is a critical skill for advanced math and algebra  -- and it's a skill that we find many students are not very good at!

It's worth investing time and practice in learning how to add and subtract negative numbers quickly and accurately.

## Understanding Integers

Integers are numbers, specically, they are whole numbers (not fractions or decimals) above or below 0.

To put it more concisely, integers are positive and negative whole numbers.

Integers can be as high ($32$ or $32,000,009,876$) or low ($-12$ or $-765,987,322,000$) as you can imagine (both positive and negative numbers go on infinitely). But, remember integers do not include any numbers with decimals ($3.45$ or $-.98$) or fractions ($5\dfrac{8}{9}$ or $-\dfrac{3}{89}$).
