Three numbers have absolute values of 2,4 and 9. The product of all the numbers is positive.

The absolute value of a number is how far away it is from 0 on a number line.

Example) 2 is two numbers away from 0, but neg. 2 (-2) is also two numbers away from 0

So basically. A positive number has the absolute value of itself. (2 = a value of 2) and negative numbers have the absolute value of the positive form of that number. (-9 = a value of 9)

Numbers that have the absolute value of 2: 2 and - 2

Numbers that have the absolute value of 4: 4 and - 4

Numbers that have the absolute value of 9: 9 and - 9

You are looking to add your numbers together to make a positive.

So the answer is the positive answers to the absolute values: 2,4,9

2+4+9=15

15 is a positive number.
