The best way to use this set, is to use it as a flash card. flip the card once you make a deci-
sion. If you use the "learn with quiz feature, it'll be pretty easy as you will have 3 different
options than the ones shown on the card.
If you are seeing this first you're good to continue.
Any calculations I do in the explanations are done with Pii as the calculator number
3.141592654
I also don't round anything until the very very end. - ANSWER The best way to use this
set, is to use it as a flash card. flip the card once you make a decision. If you see this first
without flipping the card, you need to adjust your settings.
