Opposites 

Opposites have the same absolute value-meaning they are equal distance from 0 but different signs.

When added together the numbers equal 0. They cancel each other out.

Negative Numbers

• They are on the left side of the number line. 
• When added to a positive number with the same value it equals zero 

The absolute value is the distance of the number from zero 

The higher the negative number is, the farther the number is from zero.

-4, 1, -6, 2,

• Ms.Driscoll has 150 $ in her bank account

Shuaib walked 3 miles east -> +3

Shuaib walked 3 miles west -> -3
