I want to be a software developer/engineer.?

I've been writing programs for 37 years, and all the math I ever used I learned by the time I was 17. The only time you'll need higher level math is if you're writing a program that requires it. IOW, you can't write a program to do Fourier ysis unless you can do that math yourself, But programming itself requires only simple arithmetic. (You might want to learn binary and hexadecimal notation, and get comfortable with them, but that's "how you display it", not "how you calculate it". It's like Roman numerals. 10 + 10 is 20, and if you say it in hex, it's A + A = 14. It's still twice the number of fingers on both hands. Then you'll understand "There are only 10 kinds of people, those who understand binary and those who don't.")
