The quiz shows incorrect output for 3d6.  The line reading "72 64 113
33 78 82" was mistakenly copied from a different set of dice.

"3d6" means:  (rand(6)+1) + (rand(6)+1) + (rand(6)+1)

(The +1 are because rand is zero-based, but dice are one-based.)

- is subtraction, so -4 means subtract 4.

/ is division, so /d4 means roll a d4 and divide that into the
expression left of the /

d% == d100

d00 is not valid; there is no such thing as a zero-sided die (although
if you want to make 00 an extension to imply d100 in your own
implementation, that's fine).
