Absolute Value

100

Absolute Value Is...

The distance from zero on a number line

200

True or False - Absolute Value can be negative

False

300

What is the absolute value of 7

7

400

What is the absolute value of -9.75

9.75

500

Which is greater:

-5 or the absolute value of 3.7

-5

Adding Integers

100

A negative plus a negative is always

Negative

200

-3 + 7 = 

4

300

5 + (-10) =

-5

400

-7 + (-8) =

-15

500

When adding a positive and a negative how do you know if the answer will be positive or negative?

Take the sign from the integer with the larger absolute value.
