The book that made things click for me was Maths: A Student's Survival Guide by Jenny Olive. Give it a shot, use a calculator for everything. IMO in the age of computers let computers do the calculations and just learn to have intuitions.

I'd have to be convinced that you can develop those intuitions without basic arithmetic. Mind you, I'm not saying spend a lot of time mastering long division or whatever. (I'd probably have to look up the technique myself.) But I think some level of numeric fluency is probably necessary.

“I'd probably have to look up the technique myself.”

No offense but I am pretty sure that was the point. If it’s math you forget, it’s not math worth learning. Learn what you want or need to know. The rest is dross.
