Lesson 3: 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.

• Alright i don't get how 5 - (-5) is 10 can someone please explain :(
How is it the same as adding?
• Subtracting negatives from a number means that you're adding because adding a negative number to another number [e. g. 5 + (-5)] means you're just subtracting — so, if you subtract a negative number from a number, that means you're performing the opposite of subtracting; therefore it's just the same as adding. You're welcome.

You'll understand when you're taught that.
