How Do You Use an Answer Grid?
• The correct answer can be a positive or a negative number. If the answer is a negative number, you must enter a negative sign. If no sign is marked, the answer will default to a positive number.
• The answer grid includes a floating decimal point. If the answer is a decimal number, you must enter a decimal point.
• Enter your answer in the boxes and then fill in the corresponding bubbles.
• You do not have to use all the boxes and can place your answer in any set of consecutive boxes.
• Extra zeros may be filled in (either before or after the answer) as long as their placement does not affect the value of the answer.
The grids below show 2 correct ways to enter an answer of -58.4 and two incorrect ways (marked with an X).
