“When we add two negative numbers
together, we just add the two numbers together and
put the negative sign in front of the answer! The
answer goes down on the number line!”-3 + -3 = -6
“When we add two positive numbers
together, we just add them together! The

“If the starting number is a positive, and a higher
negative number is added, then the answer will always be a negative
number!”e.g. 3 + -4 = -1

There’s 1 negative leftover!
“If the starting number is a positive, and a lower
negative number is added, then the answer will always be a positive
number!”e.g. 5 + -4 = 1

When checking our answers, you can add the starting number with the answer, and it should
equal the number between them.
e.g. 3 + -2 = 1
Adding a negative number is the same as taking away.
e.g. 3 + -2 = 1becomes3 – 2 = 1
