Depends on what kind of programing your doing and what kind of projects your working on.

As a person who isn't great a programming, has no real use for it in my daily life and forgets everything I've learned, and has pretty much given up on trying to remember what little I ever knew I was able to make a program that used Excel, an Excel compatible version of a grocery store's main supplier's invoices, and USB barcode scanner to greatly speed up checking in the 10+ pallets of stuff that would come in three days a week.

Pretty much the only math I can remember needing to use was "add +1 to value stored in incrementerVariable".

Also, as far as programming goes, you can be bad at math so long as you can remember that there is a formula to do a thing. Nobody is expecting you to remember a pile of equations, only that they exist and how to look them up when you need them.
