Intro to negative numbers

What are negative numbers? When do we use them? Where do we find them on the number line? Let's learn what happens in the world below zero!

Order negative numbers

We all know that 6 is bigger than 4, but is -6 bigger than -4? This tutorial is designed to help you compare negative numbers.

Number opposites

Opposite numbers are the same distance from 0 on opposite sides of the number line. A number opposite is sometimes called an additive inverse.

Absolute value

You'll find absolute value absolutely straightforward--it is just the "distance from zero". If you have a positive number, it is its own absolute value. If you have a negative number, just make it positive to get the absolute value. As you see as you develop mathematically, this idea will eventually extended to more contexts and dimensions, so super important that you understand this core concept now. Common Core Standards: 6.NS.C.7, 6.NS.C.7c, 6.NS.C.7d

Intro to adding negative numbers

Learn how to add negative numbers. By the end of this tutorial, you'll be solving problems like 4 + (-7) with ease!

Intro to subtracting negative numbers

Learn why subtracting a negative number is the same as adding its opposite!

Adding & subtracting negative numbers

Add and subtract negative numbers using a number line. It's the 7th grade mathematics shuffle: "Slide to the left for a negative value, and slide to the right for a positive value." Be careful, though. Which way do you move if you are subtracting a negative number? The answer awaits!

Multiplying & dividing negative numbers

You already know how to multiply and divide whole numbers, decimals, and fractions. See what happens when we throw negative numbers into the mix. It's really not so different!
