Question

Here is a list of numbers.

-45 -21 -16 12 33 40
(a) write down two numbers from the list that add up to -9

Answer 1

-21, 12

Explanation:

We first have to solve each of the list of numbers:

-45 -21 = -66

-21 - 16 = -37

-16+12=-4

33+40=73

-45-16=-61

-45+33 = -12

-45 + 12 = -33

-21 + 12 = -9

Hence, we can conclude that -21 and 12 add up to -9
