100-25

It technically equals 75, I know that know but a few hours ago i didn't...

this means 100-25. that equals 85.

7th grade science teacher: so sometimes you need to do a bit of side work. Jeffery can you do if for us (not my real name)
Me: Sure, 85... :|

7th grade science teacher: lets try that again
Me: Huh why
other classmates: Jeff, its not 85, its 75
Me: OMG *facepalm*
