The proper name for the subject is mathematics or just "math" for short. Calling it "maths" calls attention to your confusion. If you provide some examples of specific questions that you find difficult, we will try to lead you to a better understanding. Please show as many steps as you can in your thought process. Perhaps we can also suggest some helpful texts.
