Fiona's Integer Post Adding and Subtracting

This is my first post about Integers. I will be talking about Adding and Subtracting.

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:
  • A positive n and a positive will give you a positive.
  • Negative and a negative will give you a negative.
  • When the bigger number is positive and the smaller number is negative, your answer will be positive.
  • When the bigger number is negative and the smaller number is positive, your answer will be negative.
  • Zero pairs will not change the value of your question.
  • You should model your questions to check your answers.
