Deltamathing

The act of frantically studying using Deltamath when you realize that Mr. T has assigned a quiz for tomorrow

Person 1: Dude there's a Trujillo quiz tomorrow
Person 2: I know, I've been deltamathing the whole day

Deltamath 

The worst math "program" ever made, forces you to completely guess with no help if you get it wrong, just some bullshit "Your answer is not correct, please try again" absolutely useless, newer versions will deduct points from your progress if you get it wrong, absolute trash, fuck Zach Korzyk

james:yo dude i got a assignment on deltamath
mark:im warning you now, prepare for a lot of anger and frustration when using that shitty excuse for a program
