I've used much less than 5% of what I learned there, and probably more like less than 1%.

Then you went to a horrible university.

What about logic, never used it, hm? De Morgans Laws? If course, you use them all the time, you're just so used to them that you forgot the name.

Approximations (numerical mathematics)? All the time. Important as well: Understanding about error margins and how many digits in what calculation you can rely on.

Calculus, analysis, all the shitty things we hated, we use it. Fragments here and there, that's why mostly we don't notice.

Algorithms by themselves are pure math, like it or not. Heck, if we go to that level, the very idea of variables is from math.

I absolutely agree that there is a lot more that goes into a good programmer than just math, but there is a lot in math that we use daily when we write code.
