Pronumeral - a letter or symbol used to represent a number we don’t know, Coefficient - the number in front of a pronumeral. If there is no number in front, then its value is 1, since 1z and z are equal. It should be identified as a positive or negative integer., Constant - a term that does not contain any pronumerals. It is a number by itself., Term Term Term - consists of numbers and pronumerals combined with multiplication or division., Unknown - the actual number the pronumeral represents, Variable - describes an unknown number if its value can change, Expression - a collection of numbers and pronumerals combined with any mathematical operations, but without an equals sign. (e.g. 2x + 3 )., Equation - a mathematical statement stating that two expressions are equal (e.g. 2 x + 3 = 4y − 2 )., Evaluate - to find the value each pronumeral in an expression with a number to obtain a final value. (e.g. if x = 3 and y = 8 , then x + 2y evaluated gives 3 + 2 × 8 = 19), Substitute - to replace each pronumeral in an expression with a number to obtain a final value or evaluate the expression. (e.g. if x = 3 and y = 8 , then x + 2y evaluated gives 3 + 2 × 8 = 19), Terms, Variable, Expression, Coefficients,
