Do I Have to Know Math to be a Programmer?

It’s not necessary to know math to be a programmer.
 But as I said above, if you’re developing games, mathematics and physics play a large part and college level math is a requirement. But building an invoicing application does not require much beyond basic addition and subtraction.
With that said, many of the concepts in programming stem from algebraic thinking.
And from my personal experience, people who have an easy time learning mathematics and enjoy solving logic problems (be they algebra or puzzles from how to move Mount Fuji), tend to learn code quicker and enjoy it more in the long run. It takes a twisted mind, my friends.
One thing I would say is that the more math you know the more interesting are the problems you can work on. But telling someone who has never written a line of code that they should go learn algebra would be poor advice.
