Associative Property: A + (B + C) = (A + B) + C or A(BC) = (AB)C
Coefficient: the constant value multiplied to a variable in a variable term. Examples: For 3xy, the coefficient is 3. For -dwz the coefficient is -1.
Commutative Property: A + B = B + A or AB = BA
Constant: a number whose value doesn't change. Examples: 56, pi, the number of days in a week
Distributive Property: A(B + C) = AB + BC
Evaluate: find the value
Expression: any combination of numbers using operators. Examples: 2 + 3, 3x^2, 7
Factor: part of a multiplication problem
Order of Operations: the order of precedence mathematicians agree to use for computation. While some students may be familiar with "PEMDAS," many teachers are now promoting the memory tool GEMA: Grouping symbols, Exponents & roots, Multiply & divide, Add & subtract. In case of a tie, go in reading order.
Substitute: To replace one value with an equivalent one.
Term: part of an addition problem
Variable: a number whose value may change or is unknown. Examples: x, the price of strawberries, Stan's age
