Rules for Rounding Off Numbers

Click Start to change the variable values in all questions. Once you have submitted your answers for grading, you cannot resubmit answers for the same Problem Set--you must click on Start each time you return to the Problem Set to be able to submit your answers. Note: Remember to use commas and zeros as place holders for decimals. (ex. 1,000 not 1000 and 0.25 not .25).
