I have seen a lot of kids quickly pass off their 2’s, 5’s, and 10’s. These tables have an obvious pattern and are much easier to learn. Then there is a serious slow down as kids hit the 3’s, 4’s, and 6’s. By the time they get to the 7’s, 8’s, and 9’s they’ve decided that multiplication is way too hard, and math isn’t their thing.
There are thousands of algebra books out there that break down algebra to its easiest components. Many learning styles in these books are different so take the time to go through them and find one that looks like you might understand or one that accommodates your learning style. Many books explain some algebra concepts better than other. Choose a variety of books or online courses. You can get a live tutor. It will be much easier to learn from someone who s already familiar with the concepts of algebra. There are online communities where people discuss their algebra problems and help each other. Remember though that even if you are a member of one the many popular interactive algebra communities you still need to study and practice a lot.
