Properties and Vocabulary II

Master math properties & vocabulary like Identity, Commutative, Inverse, coefficient, and variable with this practice worksheet!

1. Sort the property with its definition and example. Identity Property of Addition When you add zero to any number your answer is that number. 5,325 + 0 = 5,325 Identity Property of Multiplication When you multiply any number by 1 your answer is that number. 245 x 1 = 245 Property of Zero When you multiply by zero your answer is zero. (34 + 92) x 0 = 0 Commutative Property of Addition Numbers can be added in any order and the answer is still the same. 83 + 224 = 224 + 83 2. Match the vocabulary word with its example. coefficient A number used to multiply a variable. operator a symbol that shows an operation variable a letter that takes the place of a number term a single number or variable, and numbers and variables multiplied together 3. Sort the property with its examples. Substitution Property a=3 and b=2; then a+b=5 If x=y then x and y can be substituted for each other in an equation. Inverse Property of Multiplication What you multiply by a number to get 1 5 x 1 = 1 Inverse Property of Addition Adding the opposite of a number, so the sum is zero. 10 + (-10) = 0 Property of Equality When you add, subtract, multiply, or divide both sides of an equation, the sides remain equal. n + 2 = 9; so n + 2 -4 = 9 - 4
