- 1Counting Numbers{1, 2, 3, ...}
- 2Whole Numbers{0, 1, 2, 3, ...}
- 3Integers{..., -3, -2, -1, 0, 1, 2, 3, ...}
- 4Rationalp/q : p and q are integers, q is not zero
examples: 1/2, -1/2, .5, -.5, 6, -7, 1.3333... and even 4.121212
(Repeating decimals like can be fractions. Example: 2/3=.666...) - 5Irrationalnot rational
examples: pi, 4.5965...., square root of 2,
These numbers go on and on and don't repeat. - 6Real NumbersAll rational and irrational numbers.
- 7Imaginary Numberssquare root of a negative number can't be done...so you have to ________ it.
Squaring the number makes it real. - 8Absolute ValueDistance from zero.
example:
|-5| = 5 - 9opposite numberNumbers that have the same absolute value, but a different sign.
example:
5 and -5 - 10Additive Inverse Example: The additive inverse of -5 is 5, because -5 + 5 = 0. The additive inverse of +5 is -5 as well.What you add to a number to get zero.
5 + (-5) = 0
