How Do You Add Integers Using a Number Line?
Note:
Combining integers? You could use a number line to help find the answer! In this tutorial, see how to use a number line to add together integers with the same sign and ones with opposite signs. Take a look!
Background Tutorials
-
Understand that positive and negative numbers are used together to describe quantities having opposite directions or values (e.g., temperature above/below zero, elevation above/below sea level, credits/debits, positive/negative electric charge); use positive and negative numbers to represent quantities in real-world contexts, explaining the meaning of 0 in each situation.

What are Positive and Negative Numbers?
Positive and negative numbers (and zero!) are the building blocks of math. This tutorial will introduce you to positive and negative numbers and show you their location on a number line. Plus, learn a special thing about the number zero!

Further Exploration
-
Understand subtraction of rational numbers as adding the additive inverse, p - q = p + (-q). Show that the distance between two rational numbers on the number line is the absolute value of their difference, and apply this principle in real-world contexts.
