Question 40

What is the value of 5 + (-8)?

  1. 13
  2. 3
  3. -3Bonne réponse
  4. -13

Explication

Adding a negative moves left, so a start at 5 followed by eight steps left passes zero and stops three steps beyond it. A total of 13 adds the magnitudes as though both moves ran right and ignores the direction the second addend carries.
