If you do not understand the common basics of algebra then you will literally be lost forever when it comes to this subject. Being lost in the early stages of algebra can be disastrous because there are many years of advanced algebra just knocking on your door. Once you become more confident and your comfort level increases, you can actually strengthen it by trying to apply simple algebraic applications to everyday life. You will soon find out that algebra is not quite as difficult as you may have once thought.
Practice with worksheets. Once you have mastered the flash cards, try your hand at some worksheets. Start by practicing with one number set at a time. When you have mastered all of them, try worksheets that mix up all of the number sets and see how you do. If you know your tests will be timed in school, try practicing with a timer.
