Algebra is only going to become more advanced as the years of school pass and if one has not gained full knowledge of it at its most basic level, it will be impossible to venture on. You have to algebra one step at a time. If you do these steps over and over, your brain will start to adjust and you will like it.
Learn one table at a time. Select one multiplication table to learn at a time. Start with the simple tables such as 2s, 10s, 5s, and 11s. By the time you learn the more difficult tables such as the 7s and 8s, you will already know several facts. Remember, 1 x 4 is the same as 4 x 1 so you only have to learn half of the multiplication table because the other half is just written the other way.
