I started on Wednessday setting up my linear programming equation for a project due Sunday (look Ma, no procrastinating). I spent 2 hours Wed, 2 Thur and last night I spent 4 hours trying find the error in my formula that making the equation unsovlable. I finally found it and now I need to tweak two fields because I'm not sure if my variable is right.
I am so happy I used my head and started early on this! It sucks by the way, math I really never ever want to use after the end of this semester.
