Question

PLS HELP WITH ALL !THREE! I REALLY NEED HELP!

Answer 1

1. 17

2. 20

3. 0

Explanation:

The "||" signs around the numbers indicate absolute value.

Absolute value is how far a number is from 0. Ex. The absolute value of -7 would be 7, because -7 is 7 numbers away from 0.

So in these problems, we are taking the absolute values of each number. We will also be using PEMDAS because there are multiple operations in each problem.

P - parenthesis

E - exponent

M - multiplication

D - division

A - addition

S - subtraction

--------------------------------

`2*|12|-|-7|`

⇩

`2*12-7`

`24 - 7`

`=17`

--------------------------------

`|-108| / |36|+|17|`

⇩

`108/36+17`

`3+17\\=20`

--------------------------------

`|-5|*|12|-|5|*|-12|`

⇩

`5*12-5*12`

`60-60\\=0`

Answer 2

Answer: hope this helps ♡

2 × | 12 | - | -7 | = 17

| -108 | ÷ | 36 | + | 17 | = 20

| -5 | × | 12 | - | 5 | × | -12 | = 0

Explanation:

(a negative number will become positive if it's in these brackets: |-12|= 12)

2 × | 12 | - | -7 | =

2 × 12 - 7 = (-7 becomes positive seven, +7)

24 - 7 = 17

| -108 | ÷ | 36 | + | 17 | =

108 ÷ 36 + 17 = (-108 becomes positive one hundred and eight, +108)

3 + 17 = 20

| -5 | × | 12 | - | 5 | × | -12 | =

5 × 12 - 5 × 12 = (-5 and -12 become positive five and twelve, +5 and +12)

60 - 60 = 0
