I do math all day long when I'm not in meetings. Well, now I cheat and write formulas in excel. You're the guy !!! kwg

Had I attempted those, I'd have never graduated. I've had a few instances where I needed help with a problem and gone to teachers or mathematics PhD candidates. In most instances the response has been "no problem," and they start drawing on a sheet of paper. About 20 minutes later it's "can I get back with you in the morning?"
So, it was a problem.
I took a few stat classes, and matrix algebra was the way programmers handled things. Half way though the session, and with the board half covered with equations there was usually a phrase uttered like "surely you see the relationships," That usually got nothing but blank stares in return.
I'm yet to find my way through n-dimensional hyperspace.

I just spent the day with phycologists getting a baseline of my mental decay. lots of grade school math.

I'm laughing so hard at the first post! That's me all day. After struggling in college Algebra 101 I gave up. There were 2 pretty girls in my class that seemed as dumb and dizzy as they come. We had a test one day and I studied. They were done and leaving in 15 minutes. I still had 18 problems to go. I threw in the towel for good.
But somehow I can add 3 digit figures in my head at a poker table faster than most people. And I know many college grads that can't read a ruler or a dial caliper.

I had a calculus prof in college who had tests just like that. His tests were way above what he taught. In any class of 100, there are always a couple students who can do it no matter how hard it is. He'd say if they can do it, the rest of you should, too. The engineering students had to get by him before they could go on to their upper engineering courses. They were commonly having to take his class 2 or 3 times to get through it. They weren't no engineer then .

I went to college in the early 70's. Electrical Engineering major, and calculus was my hardest class. Regular math, algebra, trig, geometry came easy, don't know why I had such a mental block for calculus, ended up never having to use it my whole career. Those days we used slide rules but electronic calculators came out during my college days, most professors wouldn't let you use them in class.
On another note my physics professor had worked at Los Alamos on the A-bomb. He was a weird duck, almost blind he had to use glasses that looked like binocular eyepieces. He could fill up a chalkboard with formulas and theories non-stop. He was so smart that he was very hard to follow, at least for the dumdums like me.

One’s ability to do math correlates pretty well with how much you can earn. Study hard boys and girls.

Show that if a is a constant ,then u(x,t)=sin(at)cos(x) is a solution to
d^2u/dt^2 = a^2*d^2u / dx^2

A score of 55 general was considered a B on the curve I had both a Calculus and a Genetics Prof at TAMU like that. 🤪

Hate is a strong word. Being born with a learning disability in math was not pleasant or wonderful. Finally figured out how to use guns to pass multiplication 7x7? Japanese rifle caliber ww2 =49 6x4? N frame s&w .44 special. After passing math I purchased my math book and all 29 of us took great joy burning our books at the flag in celebration of slaying the math monster. Really REALLY hate math. And chicken.
Bangflop! another skinning job due to .260 and proper shot placement.

I earned a BSEE degree and I remember how tough we all thought the calc and physics classes were those first few semesters. Then I went to grad school and figured out what whiney babies we were as underclassmen.

I had a Chinese trig teacher in college. He took English lessons after our class. At least once a class he would just say he can't remember the English name for a term, so just skip it. In trig, terms like sine, cosine, etc. are somewhat important. I got a C out of the class. So far 35 years later it has not come back to haunt me.
Organic Chemistry, that's the one that kicked my ass.
