3. Same Signs Rule

In this exercise, you will learn to apply the “Same Signs” rule to evaluating directed numbers. Before attempting the exercise, make sure you know the following guidelines:

  1. The “same signs” rule only applies to directed numbers that have the same signs (+ or – ).
  2. Using the same signs rule, the answer takes the repeating sign.
  3. The size of the answer is the simple sum of the numbers (when you ignore the signs).
