  1. 3. A form of simplifying by combining terms with like variables together or combining constants
  2. 5. Subtracting the same number on each side of the equation in order to produce an equivalent equation
  3. 6. To put something in "simplest form"
  4. 7. A collection of numbers, symbols, and operators (+,-,x,/) grouped together that show the value of something. Does NOT have an equal sign. Can be simplified
  5. 9. Dividing the same number on each side of the equation in order to produce an equivalent equation
  6. 11. A single number or variable, or a number and variable multiplied together. These are separated by + or - signs
  7. 13. Rules that say which operations come first in an expression
  8. 14. Multiplying a number by a group of numbers added together is the same as doing each multiplication separately
  9. 17. A number that multiplies a variable
  10. 20. To find the value of the unknown variable
  11. 21. Equations that have the same value
  12. 22. Adding the same number on each side of the equation in order to produce an equivalent equation
Down
  1. 1. Terms whose variables and exponents are the same
  2. 2. The greatest number that is a factor of all the chosen numbers
  3. 4. Multiplying the same number on each side of the equation in order to produce an equivalent equation
  4. 8. There are an infinite number of values for the variable that would make is true
  5. 10. A mathematical statement that shows that two mathematical statements are equal
  6. 12. Finding what to multiply to get an expression. Also described as the opposite of distribution by "dividing and number out"
  7. 15. An unknown value. Usually represented by a letter such as x or y
  8. 16. There is only one value for the variable that would make is true
  9. 18. There are no values for the variable that would make it true
  10. 19. A fixed value. A number without a variable
