That's clever. I never had a problem memorizing multiplication. I think we did it in 3rd grade and had to go to 10. I made it up to 15 or 16 because I was the only one done before I decided to just stop. For 9s I just remembered that there is a reverse of that number later on:
9x1 = 09; 9x10 = 90 9x2 = 18; 9x9 = 81 9x3 = 27; 9x8= 72 9x4 = 36; 9x7 = 63 9x5 = 45; 9x6 = 54
Sometimes it really is about finding a pattern.
