Hello!

Just reporting a small problem.

I reported this problem yesterday with more details.

I just want to point out that this module will accept "0pi" but not "0 pi" as answer. (I just tried 0pi and it worked but not 0 pi)

For all the other answers in that module there is a space between the value (eg "3/4") and the letters ("pi").

Thanks,

again, this website just blows my mind, and is so useful for me, thanks guys.
