How do I learn maths?

I forgot maths. I did maths for my GCSEs and A-levels, but I did bad and I want to learn maths.

Is there any book that will teach me maths? I keep coming across books by K.A. Stroud. Are they good? Should I get those?

Keep in mind this is British maths, not American math, so if there are any differences, I would prefer the British version.
