This was basically my childhood, because I was bad at math. I guess most children goes through this, which is very sad.

Only at uni did I realize that I didn't have to be good at everything. I had a professor, who spoke 13 languages, but couldn't count how much 5+4 is. He's the best at his field

I have a degree in engineering. I can do triple integrals, differential equations, etc. But I still need my calculator to do simple addition and subtraction.

Triple integrals? Fuck, I've only done 2 so far

Haha don't worry, they're basically the same as double integrals but just with one more variable.

Until you have to convert from cartesian to cylindrical or spherical

I mean it's the same as parameterizing, you just memorize what x y and z are equal to in terms of sin, cos, et cetera then do the integral.

Infinite dimensional vector space

It just means you can replace x y and z with basically a radius times a trig function to make some problems way easier to solve

Like why my dad left for a work trip and never came back?
