you know what ; you made very good points. i have been doing a lot of construction, and used the math to figure out how much material I needed. Thankfully I have now just finished remodeling the bathroom. Thank you for the answer.
Right - you’ve got it now. Doing the algebra you learned doesn’t mean you are sitting down writing “x” on a paper and solving for it...you are doing it in your head to figure out all sorts of things because you learned it and it is a part of you. You aren’t going to stop and think “I’m using what I learned in so and so’s class!” whenever you just use something you learned - for example, when you started typing your replies here, you just did it - you didn’t harken back and think of how and when you learned the alphabet, how to type, etc.
Plumbers and electricians, builders, all need knowledge of math. My field is accounting and finance so of course I have to use algebra, statistics, etc. But almost everything in life is built on math.
