WHAT IS AN INTEGER?

Integers- the set of whole numbers and their opposites (…,-3,-2,-1,0,1,2,3,…)

Opposites- the opposite of a number is found by going the same distance from zero on a number line, but in the opposite direction

- basically, you just have to change the sign to its opposite

WHAT IS AN INTEGER?

Find the opposite of the following:

9___ -11___ -56___ 32 ___

Since the whole numbers are 0,1,2,3,… and the integers are described as the whole numbers and their opposites, then the integers are: …,-3,-2,-1,0,1,2,3,…

ABSOLUTE VALUE

- Absolute Value- the absolute value of a number is the number’s distance from zero on a number line
- symbol

When you see this, it is asking for the absolute value of the number inside…12 in this case

In other words…how many units away from zero is 12 on a number line?

ABSOLUTE VALUE

Since the absolute value is asking you about distance, will it ever be negative? Can you have a negative distance?

Find the following:

DON’T GET ‘EM CONFUSED!

- Absolute Value and Opposites are often confused
- Remember….for Opposites, you change it to the opposite sign. For Absolute Value, you just make the number positive
- Try to keep them straight!
