Here are the essential concepts you must grasp in order to answer the question correctly.
Absolute Value
Absolute value refers to the distance of a number from zero on the number line, regardless of direction. It is denoted by vertical bars, such as |x|, and always yields a non-negative result. For example, |-8| equals 8, as it is 8 units away from zero.

Operations with Integers
Operations with integers involve basic arithmetic functions such as addition, subtraction, multiplication, and division. When dealing with negative integers, it is crucial to remember the rules for combining positive and negative values. For instance, subtracting a positive number from a negative number results in a more negative value.

Order of Operations
The order of operations is a set of rules that dictates the sequence in which mathematical operations should be performed to ensure consistent results. The common acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) helps remember this order. In the expression |-8 - 6|, the subtraction must be performed before applying the absolute value.
