Give (a) the additive inverse and (b) the absolute value of each number. 6

검증된 단계별 안내

Identify the given number, which is 6 in this case.

Recall that the additive inverse of a number is the number that, when added to the original number, results in zero. Mathematically, the additive inverse of a number \(x\) is \(-x\).

Apply this to the number 6: the additive inverse is \(-6\).

Recall that the absolute value of a number is its distance from zero on the number line, regardless of direction. It is always non-negative. The absolute value of \(x\) is denoted as \(|x|\).

Apply this to the number 6: the absolute value is \(|6| = 6\).

주요 개념

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

Additive Inverse

The additive inverse of a number is the value that, when added to the original number, results in zero. For any real number x, its additive inverse is -x. This concept is fundamental in solving equations and understanding number operations.

Absolute Value

The absolute value of a number is its distance from zero on the number line, regardless of direction. It is always non-negative. For a number x, the absolute value is denoted |x| and equals x if x is positive or zero, and -x if x is negative.

Real Numbers

Real numbers include all rational and irrational numbers, encompassing positive, negative, and zero values. Understanding that 6 is a real number helps apply the concepts of additive inverse and absolute value correctly within the real number system.
