> What is an example where you missed mathematical knowledge to do your job? Honestly curious, I never needed any math during programming for my job.

Basic arithmetic comes up all the time: pro-rating a monthly plan, figuring out how much to scale up or down a system in response to changes in data, figuring out when your system will run out of memory/disk.

Statistics and probability are also pretty common. I'm often calculating standard deviations and finding expected values of non uniform random variables. For example, how fast does a queue have to be to handle 1 second tasks 90% of the time, but 30 second tasks 10% of the time?

Derivatives comes with many graphics tasks, such as 3D graphics or animations.
