Math

Math is used a lot yes. However, its normally pretty basic math. addition, subtraction, multiplication, division, algebra etc. You dont normally have to have a working knowledge of more advanced math like calculus/trig. Although some pretty advanced math can be used in things such as graphics programming etc

Thank you very much Stone for your answer .. I`m a beginner web developer and a friend discouraged me saying that i really need math to be a programmer.. I know that i need some basic math but..

Math knowledge never hurts. But, that said, you are using a computer which is generally very good at doing math.

I actually majored in math in college and I'm a web developer. Basic web development only requires basic math. If you get into things like Artificial Intelligence, Machine Learning, and Data Science then high level math helps. Those are useful for things like recommender systems like what Netflix uses to recommend movies. Also math just makes you better at logic and problem solving. Basically it helps but is not a requirement.

To start out you don't need much math as previously mention. After a few years if you want to go deeper, you notice that books on "algorithms" "data structures" and "computer science" in general will borrow heavily from Discrete Math for which Calculus is a pre-req.

Thank you guys for your help !
