  1. 2. A property indicating a special way in which multiplication is applied to addition of two or more numbers in which each term inside a set of parentheses can be multiplied by a factor outside the parentheses, such as a(b + c) = ab + ac
  2. 4. The property that says that two or more numbers can be added or multiplied in any order without changing the result
  3. 7. The order in which operations in an expression to be evaluated are carried out. 1. parentheses and grouping symbols 2. exponents 3. multiplication and division in order they appear from left to right 4. addition and subtraction in order they appear from left to right
  4. 10. Expressions that have the same value
  5. 11. The largest factor that two or more numbers have in common
  6. 12. A symbol used to represent a number
  7. 14. To solve; to give a value to an expression
  8. 17. The status of an expression when it has no like terms and no parentheses
  9. 19. Terms that contain the same variables raised to the same power
  10. 21. A term without a variable
  11. 22. A branch of mathematics that involves expressions with variables
  12. 23. If you add zero to a number, the sum is the same as that number

  1. 1. Changing the grouping of numbers (associating numbers) will NOT change the value when adding. For example: (7 + 4) + 8 = 7 + (4 + 8) The associative property also works with multiplication. For example: (7 x 4) x 8 = 7 x (4 x 8)
  2. 3. The product of a number and 1 is the number itself
  3. 5. The process of writing numeric or algebraic expressions as a product of their factors
  4. 6. A number multiplied by a variable in an algebraic expression
  5. 8. A number that is expressed using an exponent
  6. 9. A combination of numbers and operations, no equal sign
  7. 13. in a power, the number that tells how many times the base is used as a factor
  8. 15. The smallest multiple (other than zero) that two or more numbers have in common
  9. 16. An expression that contains at least one variable (no equal sign)
  10. 18. Each part of an algebraic expression separated by a plus or minus sign
  11. 20. The number used as a factor in a power
