Describe a situation in which opposite quantities combine to make 0.

Hello!

A real life example would be if you would add 100 dollars in a bank account and then, subtract the 100 dollars from that account.

The equation used would be 100 + (-100) or in a simpler version 100 - 100 (They both mean the same thing!)

Hope this helps! :)))
