In class we made a movie about adding and subtracting integers. Here is my movie.

             
This is what I know about adding and subtracting integers.
  • positive + positive = positive
  • negative + negative= negative
  • positive+ negative= positive
  • negative+ positive= negative
  • negative- negative= negative/positive
  • negative- positive= negative
  • positive-negative= positive
  • positive-positive= positive/negative
  • You look for which value is higher than the other. So if your absolute value is higher that is the sign for what your answer is. 
  • If your absolute value is a negative. Then your answer will be a negative.
  • If your absolute value is a positive. Then your answer will be a positive.
  • If you add a positive and a positive together it will make a positive.
