Ignore everyone else in this thread anon, I am similar to you and can actually give you advice from experience. For one, it takes some practice and headbanging, you will feel frustrated a lot at first and itll go away with time (I'm talking years). Just practice running simpler into harder equations and compuations in your head. One thing I recently noticed is realizing the way we think so easily about words, but get tripped up on math words. Try to "mathify" your language and find the logic rules governing grammar syntax and etymologies. Then you get practice with an easier background and can convert. I recommend you work with functions as well for experience computing vast quantities of numbers at once, and for learning the significance of the Equal Sign, which is the most important concept in all of math below a certain point, and it converts to a different kind of equivalence later (logical). Remember, everything is just a thing. And lastly, read books on logic, or heavily logical math. Proof based stuff.
