  1. 4. A mathematical process that combines two or more numbers such that its product or sum equals the identity
  2. 5. Adding the same number to each side of an equation produces an equivalent expression
  3. 6. The sum of a set of numbers is the same no matter how the numbers are grouped
  4. 7. A variable that depends on other factors
  5. 9. States that when both sides of an equation are divided by the same number, the remaining expressions are still equal
  6. 13. The rules to be followed when simplifying expressions
  7. 16. the process of replacing a variable in an expression with its actual value
  8. 17. The sum of a group of numbers is the same regardless of the order in which the numbers are arranged
  9. 18. The relation between two quantities whose ratio remains constant
  10. 20. the set of all values which, when substituted for unknowns, make an equation true
  11. 21. States that when both sides of an equation are multiplied by the same number, the remaining expressions are still equal
  12. 23. A number multiplied by a variable in an algebraic expression
  13. 24. The number of times a number or expression(called base) is used as a factor of repeated multiplication. Also called the power

  1. 1. A mathematical sentence that contains an equal sign
  2. 2. The product of a set of numbers is the same no matter how the numbers are grouped
  3. 3. A quantity that does not change its value
  4. 7. The sum of two addends multiplied by a number is the sum of the product of each addend and the number
  5. 8. Terms in an algebraic expression that have the same variable raised to the same power. Only the coefficients of like terms are different
  6. 10. An equation which states that two ratios are equal
  7. 11. The product of a group of numbers is the same regardless of the order in which the numbers are arranged
  8. 12. States that when both sides of an equation have the same number subtracted from them, expressions are still equal
  9. 14. The constant value of the ratio of two proportional quantities x and y; usually written y = kx, where k is the constant of proportionality. In a proportional relationship, y = kx, k is the constant of proportionality, which is the value of the ratio between y and x
  10. 15. A mathematical phrase involving at least one variable and sometimes numbers and operation symbols
  11. 19. A variable that stands alone and isn't changed by the other variables you are trying to measure
  12. 22. A mathematical sentence that contains the symbols >,<, ≥, or ≤
