  1. 4. Both sides of an equation can be divided by the same nonzero number and the sides remain equal.
  2. 5. A variable whose value determines the value of another (dependent) variable.
  3. 6. A variable whose value changes in response to another (independent) variable.
  4. 8. The same number can be added to both sides of an equation and the sides remain equal.
  5. 9. A statement that compares two quantities using <, >, d,e, or
  6. 10. Relationships between operations that "undo" each other, such as addition and subtraction, or multiplication and division (except multiplication or division by 0).

  1. 1. Both sides of an equation can be multiplied by the same nonzero number and the sides remain equal.
  2. 2. A value of the variable that makes the equation true. Example The solution of m-15=12 is m=27, because 27-15=12.
  3. 3. The same number can be subtracted from both sides of an equation and the sides remain equal.
  4. 7. A mathematical sentence that includes an equals sign to compare two expressions. 8+4=4+4+4
