I'm having a hard time memorizing my mulitplication tables, does anyone know an efficient way to go about memorizing them? Thanks

P.S. I'm a pretty slow learner
Memorizing is rarely easy.
There are no "tricks" or magical approaches which will make it easy.
But look at it this way....MOST 3rd graders do it!!
You can, too! It takes practice.
So...if you are determined to master this, you WILL master it. Practice several times a day, several minutes at a time. CHECK your answers, and spend some extra time each day on the particular facts you've missed. Third graders typically take timed tests every week....you can take a timed test yourself. Give yourself 1 minute to do all of the "five times" facts, for example. When you can do all of those in 1 minute,
expand to another set of facts.
I'm sure you can find LOTS of online activities which will help you with this practice, such as flashcards, games, etc.
I repeat...there is no magic pill that I or anyone else here can prescribe to make this painless for you, but since literally millions of elementary school students (of all kinds of ability levels!!) do this every year, you surely can, too.
