1. The amount each consecutive term is multiplied by in a geometric sequence.
- ANSWER common ratio
2. A set of numbers or shapes arranged according to a rule. - ANSWER
pattern
3. Finding the total of two or more values. - ANSWER addition
4. Numbers or shapes in a particular order. - ANSWER sequence
5. A number whose value is greater than zero. On the number line, these
numbers are to the right of zero. - ANSWER positive number
6. A term that does not have the same variable(s) with the same exponent(s) as
another term. The terms cannot be combined using addition or subtraction. -
ANSWER Unlike Term
7. Sometimes called a power, it is a number that shows how many times the
base is multiplied by itself. For example, the 3 in 8^3. - ANSWER
Exponent
,8. In algebra, breaking an expression into its factors. These factors can be
multiplied together, producing the original expression. - ANSWER
Factoring
9. A value that is known and unchanging. - ANSWER Constant
10.A set of rules that defines the order in which mathematical operations should
be performed. - ANSWER Order of operations
11.Combining terms that have the same variable component. Combining like
terms helps to consolidate when solving an equation. - ANSWER Combine
like terms
12.The largest exponent in an expression. - ANSWER Degree
13.An operation that undoes another operation. - ANSWER Inverse Operation
14.A mathematical principle used to multiply one term by multiple terms. This
principle is employed when there are parentheses around multiple terms,
which are in turn multiplied by a single term. - ANSWER Distributive
Property
15.A string of terms that are connected by division, addition, and subtraction
operations. - ANSWER Algebraic Expression
16.When a variable is plugged back into the equation for the chosen variable
and solved. - ANSWER Substitution
, 17.Two mathematical expressions separated by the equals sign, =. The two
expressions on either side of the equals sign hold the same value as one
another. - ANSWER Equation
18.The sum of the lengths of the sides of a two-dimensional figure. -
ANSWER Perimeter
19.The result of division. - ANSWER Quotient
20.A symbol, such as x, that represents an amount or quantity that can change
value. - ANSWER Variable
21.A term that has the same variable(s) with the same exponent(s) as another
term. The term can be combined with another like term using addition or
subtraction. - ANSWER Like Term
22.What is measured in an experiment. Also called a response variable, this is
what is influenced as a result of an independent variable. - ANSWER
Dependent Variable
23.The result of one number being subtracted from another number. -
ANSWER difference
24.An integer that is not even; any integers not divisible by 2. - ANSWER odd
number
25.A set of numbers with a constant difference between consecutive terms. -
ANSWER arithmetic pattern
