WGU - D126 - Mathematics for Elementary Educators II Latest Update Graded A+ 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
