Find each sum or difference. |-8 - 6|

검증된 단계별 안내

Identify the expression inside the absolute value: |-8 - 6|. This means we first need to simplify the expression inside the absolute value bars.

Perform the subtraction inside the absolute value: calculate -8 - 6. Remember that subtracting a positive number is the same as adding its negative.

Simplify the result from the subtraction to get a single number inside the absolute value.

Recall the definition of absolute value: the absolute value of a number is its distance from zero on the number line, which is always non-negative.

Take the absolute value of the simplified number by removing any negative sign, resulting in the final value of the expression.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Absolute Value

The absolute value of a number is its distance from zero on the number line, always expressed as a non-negative value. For example, |−8| equals 8 because it is 8 units away from zero. Absolute value removes any negative sign.

Order of Operations

Order of operations dictates the sequence in which mathematical operations are performed. In the expression |-8 - 6|, subtraction inside the absolute value must be done first before applying the absolute value.

Evaluating Expressions

Evaluating expressions involves performing arithmetic operations step-by-step to simplify the expression. Here, subtracting inside the absolute value and then taking the absolute value gives the final result.
