Answer:
-15
(Negative 15)
Step-by-step explanation:
The straight line symbols, bars | | around a number are absolute value symbols. When written around a number, it means the number between the symbols changes to positive. If the number is already positive, then it stays the same.
Similar to using brackets, solve the operations between the bars first before making the number positive.
When evaluating expressions, remember to use PEDMAS or BEDMAS from left to right.
(I put more spacing between each absolute value so you can see better.)
|8| - |-4|
- |-4| - |-1-14| First number: 8 is already positive.
= 8 - |-4|
- |-4| - |-1-14| Second number: Change -4 to 4
= 8 - 4
- |-4| - |-1-14| Third number: Change -4 to 4
= 8 - 4
- 4 - |-1-14| Fourth: Solve between the bars -1-14 = -15
= 8 - 4
- 4 - |-15| Fourth: Change -15 to 15
= 8 - 4
- 4 - 15 Subtract from left to right. Simplify 8 - 4 = 4
= 4
- 4 - 15 Simplify 4 - 4 = 0
= 0 - 15 Subtract 15 from 0
= -15 Answer
