Summary: Adding Integers

Key Concepts

• Addition of Positive and Negative Integers

  [latex]5+3[/latex]	[latex]-5+\left(-3\right)[/latex]
  Both positive, Sum positive	Both negative, Sum negative
  When the signs are the same, the counters would be all the same color, so add them.
  [latex]-5+3[/latex]	[latex]5+\left(-3\right)[/latex]
  Different signs, More negatives	Different signs, More positives
  Sum negative	Sum positive
  When the signs are different, some counters would make neutral pairs; subtract to see how many are left.
