WGU - D126 - MATHEMATICS FOR ELEMENTARYEDUCATORS II 2024 NEWEST EXAM
common ratio - (correct answer) The amount each consecutive term is multiplied by
in a geometric sequence.
pattern - (correct answer) A set of numbers or shapes arranged according to a rule.
addition - (correct answer) Finding the total of two or more values.
sequence - (correct answer) Numbers or shapes in a particular order.
difference - (correct answer) The result of one number being subtracted from
another number.
odd number - (correct answer) An integer that is not even; any integers not divisible
by 2.
arithmetic pattern - (correct answer) A set of numbers with a constant difference
between consecutive terms.
term - (correct answer) 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 - (correct answer) A mathematical calculation or process. The most
common are addition, subtraction, multiplication, and division.
geometric pattern - (correct answer) A set of shapes with a repetitive order, also
known as a shape pattern.
subtraction - (correct answer) Finding the difference between values.
multiplication - (correct answer) An operation performed on two numbers that results
in a product. This operation is often denoted by the dot sign, ·.
set - (correct answer) A collection of things. In the context of math, these are usually
collections of numbers.
even number - (correct answer) An integer that is divisible by 2.
negative number - (correct answer) A number whose value is less than zero. On the
number line, these numbers are to the left of zero.
consecutive term - (correct answer) A term in a pattern or sequence that
immediately follows another term with no gaps between them.
, ellipsis - (correct answer) 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 - (correct answer) A set of shapes with a repetitive order, also known
as a geometric pattern.
positive number - (correct answer) A number whose value is greater than zero. On
the number line, these numbers are to the right of zero.
Unlike Term - (correct answer) 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 - (correct answer) 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 - (correct answer) In algebra, breaking an expression into its factors.
These factors can be multiplied together, producing the original expression.
Constant - (correct answer) A value that is known and unchanging.
Order of operations - (correct answer) A set of rules that defines the order in which
mathematical operations should be performed.
Combine like terms - (correct answer) Combining terms that have the same variable
component. Combining like terms helps to consolidate when solving an equation.
Degree - (correct answer) The largest exponent in an expression.
Inverse Operation - (correct answer) An operation that undoes another operation.
Distributive Property - (correct answer) 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 - (correct answer) A string of terms that are connected by
division, addition, and subtraction operations.
Substitution - (correct answer) When a variable is plugged back into the equation for
the chosen variable and solved.
Equation - (correct answer) 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.
