Explain how you would use a number line to find the absolute value of - 12.

The absolute value is 12. I don't know how you would use the number line to your advantage but that's because that's not how they taught me in school.

This is kind of hard to explain, but I'm going to try. Feel free to comment questions if what I'm going to say doesn't make sense.

Absolute Value

∞ # of spaces away from zero

∞ how far away a number is from zero

1). Draw a number line.

2). Label it from - 12 to 0.

3). Count on the number line from - 12 to 0 and see how many units to the right you have to go to reach zero. The answer is 12, so that is the absolute value.

|-12| = 12
