First off, teachers. Don't use this dog-$#*! excuse of a program. It may be easy to assign work using ALEKS, but trust me, those few clicks make such a difference in someone's week. Teachers only give it good reviews because it makes it easier for them. It is awful. Whoever created it should go $#*! themselves. Jean-Claude Falmagne (creator) should shoot himself, then leave a note asking for someone to hand his body where the crows will eat it. Mother$#*!er is 85 years old and still isn't wise. "It's not formal" comes after every problem where you put.[number] instead of 0.[number]. The 9th circle of hell exists only for this mother$#*!ing prune of a man. I used to love math. I don't anymore. ALEKS probably ruined my potential. Thank you for your time.
