Quizzes & Ans..
common ratio
The amount each consecutive term is multiplied by in a geometric sequence.
pattern
A set of numbers or shapes arranged according to a rule.
addition
Finding the total of two or more values.
sequence
Numbers or shapes in a particular order.
difference
The result of one number being subtracted from another number.
odd number
An integer that is not even; any integers not divisible by 2.
arithmetic pattern
A set of numbers with a constant difference between consecutive terms.
term
An individual number or variable, or numbers and variables multiplied together in an
expression, separated by addition, +, subtraction, -, or division ÷ signs. Numbers or
variables separated by an operation symbol or equal sign.
operation
A mathematical calculation or process. The most common are addition, subtraction,
multiplication, and division.
geometric pattern
A set of shapes with a repetitive order, also known as a shape pattern.
subtraction
Finding the difference between values.
multiplication
An operation performed on two numbers that results in a product. This operation is often
denoted by the dot sign, ·.
set
A collection of things. In the context of math, these are usually collections of numbers.
even number
An integer that is divisible by 2.
negative number
A number whose value is less than zero. On the number line, these numbers are to the
left of zero.
consecutive term
A term in a pattern or sequence that immediately follows another term with no gaps
between them.
ellipsis
A symbol made up of three dots (...) that is used at the end of a sequence to indicate
that the sequence is infinite, or goes on forever. Used in the middle of a sequence, it
indicates continuing.
, shape pattern
A set of shapes with a repetitive order, also known as a geometric pattern.
positive number
A number whose value is greater than zero. On the number line, these numbers are to
the right of zero.
Unlike Term
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.
Exponent
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.
Factoring
In algebra, breaking an expression into its factors. These factors can be multiplied
together, producing the original expression.
Constant
A value that is known and unchanging.
Order of operations
A set of rules that defines the order in which mathematical operations should be
performed.
Combine like terms
Combining terms that have the same variable component. Combining like terms helps
to consolidate when solving an equation.
Degree
The largest exponent in an expression.
Inverse Operation
An operation that undoes another operation.
Distributive Property
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.
Algebraic Expression
A string of terms that are connected by division, addition, and subtraction operations.
Substitution
When a variable is plugged back into the equation for the chosen variable and solved.
Equation
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.
Perimeter
The sum of the lengths of the sides of a two-dimensional figure.
Quotient
The result of division.
Variable
A symbol, such as x, that represents an amount or quantity that can change value.
Like Term
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.
