Question

What's |5| + |–7|?

Question 8 options:

A)
–12

B)
–2

C)
12

D)
2

Answer 1

The absolute value returns the "positive version" of a number. This means that if the number is already positive, it does nothing. Otherwise, it gets rid of the negative sign.

So, you have

`|5|=5,\quad |-7|=7`

and thus

`|5|+|-7|=5+7=12`

Answer 2

C) 12

Explanation:

Absolute value always means it is the positive version of the number

This switches -7 to 7 and 5 stays the same.

5 + 7 = 12
