ABSOLUTE VALUE
The Absolute Value of a number is the distance to zero.
Distance cannot be negative, so the absolute value is always positive.
Evaluate the following (ask yourself, how far is the number from zero?)

INTEGERS
Remember: Integers are the set of WHOLE numbers and their OPPOSITES.
INTEGERS
Remember: Integers are the set of WHOLE numbers and their OPPOSITES.
Positive integers are greater than zero.
Negative integers are less than zero.
***Zero is neither positive nor negative!*** _________________________________________________________________________ COMPARING INTEGERS
The further a number is to the right of the number line, the greater it's value. Let's compare some integers! Look at the integers -3 and -1. Is -3 larger or smaller than -1? Graph the numbers on the number line. _________________________________________________________________________
What about 2 and -5? Graph them on a number line and you will see that 2 > -5. _________________________________________________________________________ What about 0 and -2? Graph them on a number line and you will see that 0 > -2. _________________________________________________________________________ ORDERING INTEGERS
When ordering integers from least to greatest follow the order on the number line from left to right. Example: Order from least to greatest 4, -5, 0, 2 4, -5, 0, 2 ordered from least to greatest is -5, 0, 2, 4.
4, -5, 0, 2 ordered from greatest to least is 4, 2, 0, -5 (notice when ordering from greatest to least we follow the numbers from right to left on the number line) _________________________________________________________________________ MORE EXAMPLES Order from least to greatest 15, -9, -3, 5 Answer: -9, -3, 5,15 Order from greatest to least -16, -7, -8, 2 Answer: 2, -7, -8, -16 |
