Re: [Tuxmath-devel] Factoroids number generation

[sasayins <sas...@gm...>]

Hi David,

I think I remembered someone from GCI contributors posted here a bug related
to that issue. And also I noticed when I played the fraction section in
factoroids the number 2 is only available and some fractions need some other
number to simplify. I think the new prime gun implementation affected the
fraction game.

kiko
