the only way to over come phobia is by facing. If you really want to learn maths, you look for a friend who knows it so you learn from him/her cos u feel more free when you learn from your pals or better go get a maths textbook that breakdown every steps for easy understanding. I have always love maths hope this idea helps....
One way is to be in an an environment where you do not feel like people might make fun of you if you make a mistake. Then practice, practice, practice!!! You can do both of those things at the Khan Academy, which is free and very popular. Even Bill Gates gave them a lot of money.
Face your fear :)
Ask a teacher for after school help or get a tutor. I used to be scared of math too, but after getting after school help I realized it wasn't so bad!
I agree with kahili and billyshear... Khan academy is awesome... It really helped me and so did an after school tutor :)
using an injection!! :O>
