  • Front
  • Back
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.
algebra
arithmetic operations using letters and/or symbols in place of numbers.
algebraic expressions
expressions composed of letters to stand for numbers.
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.
empty set
a set with no members (a null set).
equal sets
sets that have exactly the same members.
equation
a balanced relationship between numbers and/or symbols. A mathematical sentence.
equivalent sets
sets that have the same number of members.
Euler circles
a method of pictorially representing sets.
evaluate
to to determine the value or numerical amount.
exponent
a numeral used to indicate the power of a number.
extremes
outer terms.
factor
to find two or more qualities whose product equals the original quantity.
finite
countable. Having a definite ending.
F.O.I.L. method
method of multiplying binomals in which first terms, outside terms, inside terms, and last terms are multiplied.
function
a relation in which each element in the domain is paired with exactly one element in the range
graphing method
a method of slving simultaneous equations by graphing each equation on a coordinate graph and finding the common point (intersection).
