1 Properties of Algebraic Notation Unit 4 VocabularyProperties of Algebraic Notation
2 ExpressionOne or more numbers, variables, or numbers and variables with one or more operations.a + 1 a - b 3x / b
3 EquationA statement that two expressions are equal. It has an equal sign.X + 2 = 6
4 Terma number, variable, product, or quotient in an expression. Each term is separated by an operation sign.
5 SimplifyTo combine like terms and perform operations until all terms have been combined.
6 Identity PropertyThe product of 1 and any number equals that number.
7 Distributive Property You can multiply a sum by a number, or multiply each addend by the number and ad the products, to get the same result.
8 Commutative PropertyChanging the order of the addends/factors does not change the sum/product. (Only works for addition and multiplication)
9 Associative PropertyGrouping the addends/factors in different ways does not change the sum/product.(Only works for addition and multiplication)
10 Order of Operations: When more than one operation is present. Remember: PEMDAS (Please Excuse My Dear Aunt Sally)ParenthesisExponentsMultiplyDivideAddSubtractOperations inside parenthesis are performed first.Then multiply and divide from left to right.Then add and subtract from left to right.
11 Any number whose only factors are 1 and itself. Prime numberAny number whose only factors are 1 and itself.Ex. 2, 13, 17
12 A whole number that has more than two factors. Composite NumberA whole number that has more than two factors.Ex. 4, 8, 81
13 Two or more numbers that can be multiplied together to make a product. FactorsTwo or more numbers that can be multiplied together to make a product.4 x 3 =12
