Question

Evaluate |-15| + |-6|.

Answer 1

21

Explanation:

The absolute value of an expression is its distance from 0.

For example, take the number -5:

<-------|------------------|------------->

-5 0

It is 5 units to the left of zero, so its absolute value is 5, NOT -5 because distance is always positive, no matter the direction.

To evaluate the given expression, first find each absolute value:

`|-15| = 15, \, \, \, \, \, \, |-6| = 6`

Then, simplify:

`|-15| + |-6| \\ =15 + 6 \\= 21`

So, the evaluated expression is 21.
