Question

Evaluate the following.
|4-7|=
|4|-7=

Answer 1

1. 3
2. -3

Explanation:

1) Value of |4 - 7| is?

→ |4 - 7|

→ |-3| = 3

Thus, the answer is 3.

2) Value of |4| - 7 is?

→ |4| - 7

→ 4 - 7 = -3

Thus, the answer is -3.

Answer 2

|4 - 7| = 3

|4| - 7 = -3

Explanation:

Absolute values are just the distance from zero. If a number is negative, then it becomes positive, and if a number is positive it stays positive, since distance is positive.

We first evaluate the stuff inside the absolute value. So |4 - 7| = |-3| = 3

For |4| - 7, we already have one value in the absolute value.... which is 4 and the absolute value of that is 4, so we get 4 - 7 = -3
