Capitolo 1, Problema 52
Give (a) the additive inverse and (b) the absolute value of each number. 0.16
Guida verificata passo dopo passo1
Identify the given number, which is 0.16.
To find the additive inverse of a number, change its sign. So, the additive inverse of 0.16 is \(-0.16\).
Recall that the absolute value of a number is its distance from zero on the number line, always non-negative.
Since 0.16 is already positive, its absolute value is simply \(0.16\).
Summarize: (a) Additive inverse is \(-0.16\), and (b) absolute value is \(0.16\).

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
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 properties.

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.
