Things to remember when answering questions:

• Always put a zero before a decimal if there is no whole number.
  For example, put "0.5" instead of ".5".
  
• Do NOT enter commas for large numbers.
  For example, put "1000" instead of "1,000".
  (Commas are used when listing sets of numbers.)
• Always use a horizontal fraction bar.
• When you see an equal sign, the equation must be equal on both sides.
• When finding the value of a variable, you should write your answer as "x= ".
  
• Rounding should be the very last step you do (if necessary!).
