|
base
|
the number below an exponent - in 5 squared (5 to the 2nd power), it is 5
|
|
|
exponent
|
a mathematical notation indicating the number of times a quantity is multiplied by itself
|
|
|
perfect square
|
the product of a number multiplied by itself
|
|
|
power of a number
|
these are obtained by multiplying a number by itself, e.g. 3x3, 3x3x3, 3x3x3x3, etc.
|
|
|
square root
|
a number that when multiplied by itself equals a given number, e.g. 10x10=100, so the square root of 100 is 10

|
|
|
expression
|
a group of symbols that make a mathematical statement
|
|
|
grouping symbols
|
symbols such as parentheses or brackets that indicate that the operations within them should be done first.
|
|
|
order of operations
|
the mathematical rule which determines in which order you do the various operations(multiplication, subtraction, square roots, etc.) in a math problem.
|
|
|
rational number
|
an integer or a fraction. Non repeating decimals like pi, and square roots of many numbers are irrational.
|
|
|
additive identity property
|
zero added to any number does not change the number, e.g. -5+0=-5
|
|
|
associative property of addition
|
changing the grouping of the numbers in a sum does not change the sum, e.g. (a + b) + c = a + (b + c)
|
|
|
associative property of multiplication
|
changing the grouping of the numbers in a product does not change the product, e.g. a x (b x c) = (a x b) x c
|
|
|
commutative property of addition
|
in addition you can use the numbers in any order.
|
|
|
commutative property of multiplication
|
in multiplication you can use the numbers in any order.
|
|
|
distributive property
|
adding two numbers and then multiplying by another yields the same result as multiplying each one by the number and then adding the products, e.g.: a(b + c) = ab + ac.
|
|
|
identity elements
|
numbers which do not change the value of a given number. 0 is the identify element for addition, 1 is the identity element for multiplication
|
|
|
inverses
|
math functions that undo each other, e.g. the inverse of addition is subtraction
|
|
|
multiplicative identity property
|
any number multiplied by 1 is unchanged
|
|
|
multiplicative inverse property
|
if you multiply a number by it's reciprocal, or opposite, the total will equal one, e.g. 3 x 1/3 = 1
|
|
|
multiplicative property of zero
|
any number multiplied by 0 is 0
|
|
|
reciprocal
|
a mathematical expression or function so related to another that their product is one; e.g. 4/5 x 5/4 = 1
|
