You don't always have to understand something to use it (though it

certainly helps).

So you can find a math solution and plug it into a block of code without

being an expert on that sort of math.

yes, often done.

although, usually I would think being able to understand it well enough to

effectively make use of its properties would still count as understanding

it.

It is (of course) possible to get into big trouble doing that as well,

especially if you have a numerically unstable algorithm and you give it

inputs in the unstable range. (IOW there are many algorithms that are

mathematically correct but will give horrible results when a farily

simple alternative would have given the right answer).

granted, this addresses one side of the problem:

using mathy stuff in programming.

but, doesn't really address the other side:

why an otherwise decently skilled programmer would do horridly in math

classes, even after having worked with much of the same math in the sense as

given above...

I guess that it is simply math phobia of some sort, where some kind of

inner reluctance prevents your normal ability from solving things you

are easily capable of.

My youngest son is very intelligent, but he freezes up when he sees a

complicated looking mathematical expression. He has no such difficulty

in other areas. I know many other people like that.
