coefficient In mathematics , a coefficient is a multiplicative factor in some term
of an expression(or of a series); it is usually a number, but in any case does not involve any variables of the expression.
5x – 3: Here 5 is the coefficient of the linear term 5x.
Exponent The exponent of a number says how many times to use the number
in a multiplication. 82 = 8 × 8 = 6
domain In mathematics, the domain of definition or simply the domain of a
function is the set of "input" or argument values for which the function is defined. That is, the function provides an "output" or value for each member of the domain.
factors Factors are numbers you can multiply together to get another
number
baseThe number that is going to be raised to a power.
Variable A symbol for a number we don't know yet. It is usually a letter like x
or y.
originThe starting point.
On a number line it is 0On a two-dimensional graph it is where the X axis and Y axis cross, marked ,0) on the graph here
Integers
an integer is just a whole number anything that is not a decimal or fraction
Graph In mathematics, a graph is a representation of a set of objects where
some pairs of the objects are connected by links
Additive inverse What you add to a number to get zero.
The negative of a number.
quadrantAny of the 4 equal areas made by dividing a plane by an x and y axis
(as shown).
Formula a formula is an equation that expresses an idea or theory.
Linear equation A linear equation is an algebraic in which each term is either a constant or the product
of a constant and (the first power of) a single variable Linear equations can have one or more variables. Linear equations occur with great
regularity in applied mathematics . While they arise quite naturally when modeling many phenomena, they are particularly useful since many non-linear equation may be reduced to linear equations by assuming that quantities of interest vary to only a small extent from some "background" state. Linear equations do not include exponents.
Two-step equationA two-step equation is as straightforward as it sounds. You will need to
perform two steps in order to solve the equation.
Percent
In mathematics, a percentage is a number or ratio as a fraction of 100.
Multiple
The result of multiplying a number by an integer
L.C.MThe smallest number that is a multiple of two or more numbers.
G.C.FThe highest number that divides exactly into two or more numbers. the GCF of 12 and 30 is 6, because 1, 2, 3 and 6 are factors of both 12
and 30, and 6 is the greatest.ber that divides exactly into two or more numbers.
COMMON DENOMINATORWhen two or more fractions have the same denominator (the number
on the bottom).
EQUIVALANT FACTIONSFractions which have the same value, even though they may look
differentExample 1/2 and 2/4 are equivalent, because they are both "half“
Terminating decimal
A decimal number that has digits that do not go on forever. .25
reciprocalTo get the reciprocal of a number, just divide 1 by the number
multiplicative inverseWhen you multiply a number by its "Multiplicative
Inverse" you get 1.Example: 8 × (1/8) = 1
Compatible numbersCompatible numbers are numbers that are close in value to the actual
numbers and easy to add, subtract, multiply, or divide mentally.
Like fractionsThe different fractions with the same denominator
are like fractions
