Is it necessary to learn maths to enter into programming?
pmarin: Don't worry, you will not need them at the begining. When you find some problem where you need maths just learn about it (the wikipedia is nice place to start). The problem is to identificate which maths fields you need to solve de problem.
I think that programing is a good motivation to study maths, for example I didn't care about graph teoric, trees or logic until I found that they are a great tools to solve problems. 
Just learn maths by programming.
