Let's remember!

• Your variables should follow what is given (if it is lowercase, then it must be lowercase).

  
  

• Be sure to look for the "SWITCH" words THAN, FROM, and (added/subtracted) TO. These indicate a switch of terms.

  
  

• Multiplication expressions do not have a sign. It should always be number first then variable attached. Example s multiplied to 9 is 9s

• If "to the power of," do not forget this expresses an exponential expression. Therefore you would use the raise to the power of symbol which is ^

  Example: a number y raised to the power of three is y^3
