Question

Which two integer values for n make this equation true?|n| = 1

Answer 1

For this exercise, you need to remember the definition of Absolute Value.

The Absolute Value of a number is defined as its distance from zero on the Number Line. By definition, a distance cannot be negative, therefore, the Absolute Value of a number is always a positive.

By definition, the set of Integers contains the positive numbers, the negative numbers are zero,

In this case, you have the following equation:

`|n|=1`

Notice that the Absolute Value of "n" (which is an Integer), is equal to 1.

Then, based on the definitions explained before, you know that:

`\begin{gathered} |1|=1 \\ \\ |-1|=1 \end{gathered}`

Therefore, the answer is:

`\begin{gathered} 1\text{ and }-1 \\ \\ \end{gathered}`
