So lately, I’ve been seeing a lot of things making fun of cashiers or other people being unable to do mental math, and I just wanna say, to everyone who mocks those people, or who thinks they’re stupid, or who “worry for their generation” when someone can’t mentally work out, say, how much change you get if you give them $10 when your order was like $7.38?

FUCK YOU. No, really. Fuck you.

Those cashiers aren’t “stupid”, they aren’t “being lazy”, they aren’t uneducated. Guess what? SOME PEOPLE CANNOT DO MENTAL MATH. At all. Their brains just cannot process it and so if you break their concentration or give them something beyond the very basic 10s or what not? They naturally are going to get confused.

I had a mental test today which tested me with mental math. Counting down from 100, we subtracted 7 each time. You know how far I got before I completely lost track and got confused? 93. That’s right, just the second time I didn’t know what to do. Because hey, guess what, I can’t do mental math. My brain isn’t wired that way.

So if you mock someone for not knowing how to count anything in their heads, regardless of what it is? You’re a terrible, shitty person.

Folks often act like you need to be some sort of math genius to be a computer programmer, but in practice, I find that my skills as a writer end up helping me more than my skills as a mathematician.

Programming is basically explaining what you want to happen.

Just, like, you’re explaining it to a helpful but exceedingly literal-minded space alien from the Eleventh Dimension who’s only had physical existence described to them, so you need to choose your words carefully!

Some study tips for lazy students like me:

Make an aesthetic study table, get everything you need so you don’t need to get up repeatedly. Keep everything on your table organised and aesthetically pleasing.

Before you start, skim through all the content you plan to study. Try learning the challenging concepts first. Don’t miss out on anything, make a checklist.

Timetables suck. Keep a clock on your study table and keep adjusting your time e.g you finish half a chapter in an hour then add another hour and 15 minutes to complete and the rest revise at the end.
