Tried being normal once, didn't take....I think it was a Tuesday.
Problem solving. It is core to all problems. Find projects and work through the details, with an eye towards finding good techniques. This will help build core skills.
Work through a regular high school math curriculum, with a focus on word problems. They may seem lame, but they train thinking skills.
And learn to use a computer spreadsheet. They can be useful when working out something complex, like spiral stairs.
For example: If you lean a 15' ladder against a 12' wall, how far can the foot of the ladder be from the base of the wall?

was a word printed in large letters across the wall of our maths classroom. After the first couple of years I knew I'd never forget it
Sine X = O/H
Cosine X = A/H
Tanget X = O/A

Average spoonfed fabricators will rarely need trig, as drawings are so good these days, and tricky parts are often CNC cut these days.
Good fabricators will definitely use trig and geometry
i dont like kahn academy. just try maybe...

will help build your intuition.i used to watch some of it back in the day.... all u need is an ounce of intuition and u can figure out anything in the world, even make up your own formulas. Maybe a little more than an ounce, but you get the idea. That kahn guy drives me crazy, ooph..
And if your feeling over the top, try 3brown1blue or numberphille , but if you dont get it, downt worry, i really dont understand much of 3brown1blue, a little over my head sometimes, just watch it too help your visualization/intution/spatial skills https://www.youtube.com/channel/UCYO...17AJtAw/videos https://www.youtube.com/user/numberphile/videos
remeber, its all about visualizing stuff, then everything else will click and fall into place, rather than blindy trying too look at a bunch of videos on a bunch of different math topics, when they are all very similar. Also if its daunting, dont worry, youll get there with enough practice, i promise, just like welding, in a sense. We are all in the same boat I am trying to learn some of the strength of materials stuff/beams/columns/shear in the machinists handbook and it is crazy complicated. But most of the times, u can get by with a little guesswork and trial and error then pulling out a fancy formula, except the times when its worth its weight in gold.

When I was working as a Liaison Engineer (writing repairs for rejectable aircraft parts) I got a tag for an out of tolerance anti-icing duct. The duct was around 6" in diameter, very thin walled (probably around 10-15 thou) and flexible. The inspector reported the diameter with a number that went out to 4 decimal places. I got excited thinking of the exotic piece of measurement equipment that could hold this duct round and read the diameter accurate to within one ten thousands of an inch. When I asked the inspector to show me he whipped out his "pi tape" and said he wrapped it around the pipe and got a number. It ended in a fraction, which he put it in his calculator - 4 decimal places!
