Question

Evaluate the expression

Answer 1

Facts about absolute values:

• The absolute value of a number is always positive.
• If the question asks to find the absolute value of a negative integer, the result will be the number's opposite.
• If the question asks to find the absolute value of a positive integer, the result will be the number itself.

We know that:

• Given expression: I-12I

This question is asking to find the absolute value of a negative integer. As said above, the result will be the negative integer's opposite.

• => -12's opposite is 12.

The absolute value of -12 is 12.
