a math 7 vocabulary word powerpoint with definitions and examples

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

base The 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.

origin The starting point. On a number line it is 0 On 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.

quadrant Any 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 equation A 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.M The smallest number that is a multiple of two or more numbers.

G.C.F The 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 DENOMINATOR When two or more fractions have the same denominator (the number on the bottom).

EQUIVALANT FACTIONS Fractions which have the same value, even though they may look different Example 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

reciprocal To get the reciprocal of a number, just divide 1 by the number

multiplicative inverse When you multiply a number by its "Multiplicative Inverse" you get 1. Example: 8 × (1/8) = 1

Compatible numbers Compatible numbers are numbers that are close in value to the actual numbers and easy to add, subtract, multiply, or divide mentally .

Like fractions The different fractions with the same denominator are like fractions
