| Some suggestions: (1) Make pi to the "first four digits after the decimal," rather than what you have. (2) As per cuendillar and RemoveTomorrow, you need some alternate answers for the fraction ones: With a zero before the decimal, and the actual, correctly rounded answers. In fact, you should *use* the correctly rounded answers and only allow the ones you have right now as alternates. (3) Take out the "(only 3 numbers) lol" on 3/8. Please. (4) Perhaps some reciprocal trigonometric functions? (5) Since you're already quizzing on pi, how about e? |
