what is the difference between -6 and 15 on a number line

Answer 1

Hi Meadow,

To solve this, you must subtract either one of the numbers from the other, then take the absolute value.

The easiest way is to subtract -6 from 15, since it will allow you to work with positive numbers.

So you do 15 - (-6), which is the same as 15 + 6. The answer is 21, and since it is a positive number, no further calculations are required to find the absolute value.

The difference is 21.
