Like asquaredb had done on the ns page, let us begin a MATH MARATHON on this forum.
Follow the same rules on the ns page....
Ask your questions here.
One thing:
If it gets too cumbersome here, start a MATH MARATHON CONT'D!
My question:
How often do you use the calculator on the math test - on average?
(Not only generic qs; you can also ask math qs...)
