irrational numbers
Basically pie or root but root 4 can be rational
Rational Numbers can be represented by?
Includes: Whole Numbers, Positives/Negatives, Zero, and all decimals that either terminate or repeat.
All the sets of numbers
Real, rational, integers, whole, natural
Commutative Property
The property that says that two or more numbers can be added or multiplied in any order without changing the result. XY = YX or 2 + 3= 3 + 2
Distribution Property
a(b+c) = ab + ac
Associative Property
Changing the grouping of numbers will NOT change the value. For example: (7 + 4) + 8 = 7 + (4 + 8) also works with multiplication
Additive Identity
a + 0 = a or x + 0 = x basically just saying if you add zero it keeps the number the same
Multiplicative Identity
When any number is multiplied by 1, the product is the number 2 (1) = 2 or x (1) = x
Additive Inverse
The opposite of a number. When added together, the sum is zero. 2 + -2 = 0 or x + -x =0
Multiplicative Inverse
Two numbers with a product of 1. For example, the multiplicative inverse of 2/3 is 3/2. X ( 1 / x) = 1
