I'm not looking for a general discussion on if math is important or not for programming .
Instead I'm looking for real world scenarios where you have actually used some branch of math to solve some particular problem during your career as a software developer...

Discrete math for everything, linear algebra for 3D, analysis for physics especially when trying to simplify conditionals
I've also occasionally written out truth tables to verify since there is no built-in support in the .NET libraries.....

In your experience as a practicioner, what's the most useful math knowledge for a programmer? If "it depends", what's your field of expertise and what do you need there most as far as math is concerned?
Can you point to any learning material for a beginner...

I've used all of the math .
I kinda wanna just play the "college" card.
There are tons of good textbooks out there for all maths rules I've learned so far.
Graph theory and "discrete math" that often.

I'm not sure if this is for SO or not. I am reading some of my old math textbooks and trying to understand math in general. Not how to figure something. I can do that but rather what is it that math is doing.
I'm sure this is painfully obvious but I never...

I'm just after reading Jeff's 'Five Things You Didn't Know About Me (and my office)' blog entry on Coding Horror and right at the bottom of this page he mentions (to my surprise) that he is terrible at math:

I am terrible at math and yet I get paid to write software.
It depends -- are you counting knowing how to use formulas part of math?
I think you need to be able to solve problems and that usually involves algorithms and formulas.

I am sure many developers here -- at least the ones who were formally trained -- took a fair amount of math courses in the university. Some minored in mathematics. The curriculum usually included Calculus (level 1, 2 and 3), linear algebra, probability...

My use of math is limited mostly to understanding the source uses 3D math from time-to-time, but the tools and libraries deal with most of the hard math these days bang.
That depends a lot on what you do.

Hi all,
I want to generate a truth table for the given input.Suppose if i give input 2 the output will be
10 01 11 00
if the input is 3 the output will be
111 000 110 101 011 100 001 010
i have a code snippet

This is an iterative solution:
#!/usr/bin/perl use strict; use warnings; use Math $bits = $it->()) ) { print "$bits\n"; } sub make_it { my ($n_bits) = @_; my $limit = Math::BigInt->new('2'); $limit->blsft(....

There was a thread that got derailed slightly not long ago on the subject of math. Since I can't remember what that thread was to post this summation of what algebra, aka magic math, means to me, I'll post this here.

Too bad math teachers don't use concrete and practical problem examples when they teach a solution.
