abscissa
|
the distance along the horizontal axis in a coordinate graph.
|
|
absolute value
|
the numerical value when direction or sign is not considered. the symbol for absolute value.
|
|
additive axiom of equality
|
if a=b and c=d, then a+c=b+d.
|
|
additive axiom of inequality
|
if a>b, then a+c>b+c.
|
|
additive inverse
|
the opposite (negative) of a number. Any number plus its additive inverse equals 0.

|
algebraic fractions
|
fractions using a variable in the numerator and/or denominator.
|
|
ascending order
|
basically, when the power of a term increases for each succeeding term.
|
|
associative property
|
grouping of elements does not make any difference in the outcome. Only true for multiplications and addition.
|
|
axioms of equality
|
basic rules for using the equal sign
|
|
binomial
|
an algebraic expression consisting of two terms.
|
|
braces
|
grouping symbols used after the use of brackets. Also used to represent a set. { }
|
|
brackets
|
grouping symbols used after parentheses. [ ]
|
|
canceling
|
in multiplication of fractions, dividing the same number into both a numerator and a denominator.
|
|
cartesian coordinates
|
a system of assigning ordered pairs to points on a plane.
|
|
closed half-plane
|
a half-plane that includes the boundary line and is graphed using a solid line
|
|
closed interval
|
an interval that includes both endpoints or fixed boundaries
|
|
closure property
|
when all answers fall into the original set.
|
|
coefficient
|
the number in front of a variable. For example: 9x, 9 is the coefficient
|
|
common factors
|
factors that are the same for two or more numbers.
|
|
commutative property
|
order of elements does not make any difference in the outcome. Only true for multiplication and addition.
|
|
complex fraction
|
a fraction having a fraction or fractions in the numerator and/or denominator
|
|
composite number
|
a number divisible by more than 1 and itself ( such as 4 ,6 ,8 ,9 ...). 0 and 1 are not composite numbers.
|
|
conjugate
|
the conjugate of a binomial contains the same terms, but the opposite sign between them. (x+y) and (x-y) are conjugates.
|
|
coordinate axes
|
two perpendicular number lines used in a coordinate graph.
|
|
coordinate graph
|
two perpendicular number lines, the x axis and the y axis, creating a plane on which each point on a coordinate is assigned a pair of numbers.
|
|
coordinates
|
the numbers that correspond to a point on a coordinate graph.
|
|
cube
|
the result when a number is multiplied by itself twice. Designated by the exponent 3 (such as x3 or x-cubed)
|
|
cube root
|
the number that when multiplied by itself twice gives you the original number. For example, 5 is the cube root of 125.
|
|
denominator
|
everything below the fraction bar in a fraction
|
|
descending order
|
basically, when the power of a term decreases for each succeeding term.
|
|
direct variation
|
when y varies directly as x or y is directly proportional to x.
|
|
discriminant
|
the value under the radical sign in the quadratic formula. [b2-4ac].
|
|
distributive property
|
the process of distributing the number on the outside of the parentheses to each number on the inside. a(b+c) = ab+ac.
|
|
domain
|
the set of all first coordinates from the ordered pairs.
|
|
element
|
a member of a set.
|
|
