GameCalc is just like any other game - start with limited powers, practice with those powers, and unlock stronger, more complicated skills. But in GameCalc, your first three powers are 1, +, and -. The amazing powers of 3, *, ^, and even sin are all unlockable - just derive them! Some are easy (you probably could have guessed 1+1 unlocks 2), some require a bit of thinking (how would you unlock * with +... maybe repetitive adding...), and even some basic functions become difficult to derive (no shame if division trips you up, it gave us a hard time too).
Flex your math muscles! Explore the definition of the functions and operations we take for granted. Look up what you don't know. And of course, have fun.
More functions (including derivatives and integrals) are all on the way!!
