As with any subject, the best way to study math depends upon your preferred learning style. Once you have identified the method of learning that best suits your individual personality, you can apply the techniques of that methodology to your math content to make your studies interesting and effective.
If you learn best when you see the information, you might make posters or notecards with the information you are learning. Use color-coding to help with organizing the facts. Create tables or diagrams or charts to help you see how the parts of the material relate to each other.
If you are an auditory learner and need to hear things to remember them, make up song lyrics or raps with the information you need to know and repeat them to yourself whenever possible. If your textbook has an audio version on the internet, take advantage of this and listen to it when you are reviewing.
If you learn best with your hands, make physical representations for your information. Build three-dimensional models of geometric forms. Cut out symbols or numerals for formulas from sandpaper and reassemble them on paper so you can trace and feel the forms of the variables. Use cards, counters, beads, whatever you have available and find helpful to allow you to manipulate the basis of the information you need to learn.
