Algebraic Expression |
a mathematical phrase that can contain ordinary numbers, variables (like x or y) and operators (like add,subtract,multiply, and divide |
|
Numerical Expression |
A numerical expression is a mathematical phrase involving only numbers and one or more operational symbols. |
|
Simplest Form |
A fraction is in simplest form when the top and bottom cannot be any smalle |
|
Like Terms |
"Like terms" are terms whose variables (and their exponents such as the 2 in x2) are the same |
|
Evaluate |
form an idea of the amount, number, or value of; |
|
Variable |
A variable is a quantity that may change within the context of a mathematical problem |
|
Constant |
A fixed value |
|
Term |
n Algebra a term is either a single number or variable |
|
Product |
product is the result of multiplying |
|
power |
A power is the product of multiplying a number by itself |
|
order of operations |
A power is the product of multiplying a number by itself |
|
open sentence |
In mathematics, an open sentence is described as "open" in the sense that its truth value is meaningless |
|
equations |
a statement that the values of two mathematical expressions are equal |
|
additive identity |
additive identity of a set which is equipped with the operation of addition is an element which, when added to any element x in the set, yields x. |
|
additive inverse |
additive inverse of a number a is the number that, when added to a, yields zero |
|
multiplicative identity |
multiplicative inverse or reciprocal for a number x, denoted by 1/x or x−1, is a number which when multiplied by x yields the multiplicative identity,
|
|
multiplicative property of zero |
multiplication property states that the product of any number and zero is zero. It doesn't matter what the number is, when you multiply it to zero, you get zero as the answer. So: 2 x 0 = 0. |
|
multiplicative inverse property |
multiplicative inverse or reciprocal for a number x, denoted by 1/x or x−1, is a number which when multiplied by x yields the multiplicative identity, |
|
reflexive property |
eflexive property of equality simply states that a value is equal to itself. Further, this propertystates that for all real numbers, x = x. |
|
symmetric property |
Symmetric Property of Equality. The following property: If if a = b then b = a. |
|
transitive property |
Transitive Property of Equality. The following property: If a = b and b = c, then a = c. |
|
substitution property |
f you ever plug a value in for a variable into an expression or equation, you're using theSubstitution Property |
|
commutative property |
Commutative property is one of the basic properties of numbers. The word "commute" means "exchange" or "swap over" Commutative property states that numbers can be added or multiplied in any order. |
|
associative property |
associative property states that you can add or multiply regardless of how the numbers are grouped. |
|
distributive property |
distributive property of multiplication which states that the. Definition: The distributive property lets you multiply a sum by multiplying each addend separately and then add the products. |
|
continuous graph |
That graph is a continuous, unbroken line. Therefore we want to say that f(x) is a continuous function |
|
discrete graph |
Discrete data is counted. The description of the task is usually preceded by the words "number of...". |
|
vertical line test |
Come on you know this one |
|
range |
The difference between the lowest and highest values. In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9, so the range is 9 − 3 = 6 |
|
function |
1. a relationship or expression involving one or more variables. "the function (bx + c)" 2. 3. 4. |
|
domain |
The set of values of the independent variable(s) for which a function or relation is defined. Typically, this is the set of x-values that give rise to real y-values |
|
relation |
relation between two sets is a collection of ordered pairs containing one object from each set. If the object x is from the first set and the object y is from the second set, then the objects are said to be related if the ordered pair ( x , y ) is in the relation. |
|
coordinate plain |
The plane determined by a horizontal number line, called the x-axis, and a vertical number line, called the y-axis, |
|
x axis |
horizontal line on a coordinate plain |
|
origin |
(0,0) |
|
ordered pair |
ordered pair is a pair of numbers used to locate a point on a coordinate plane |
|
mapping |
map is used to mean a function, sometimes with a specific property of particular importance to that branch |
|
function notation |
|
|
dependent variable |
|
|
independent variable |
|
|
y axis |
vertical line on a coordinate plain |
