Lesson 7: Intro to subtracting negative numbers

# Graphing negative number addition and subtraction expressions

Graph addition and subtraction expressions involving negative numbers on the number line. When we add a positive number, we move to the right on the number line. When we add a negative number, we move to the left. When we subtract a number, we move in the opposite direction as we would to add the same number. Created by Sal Khan.
