I was taught to memorize some times tables but my dad told me it was a waste with 9s (0-10) as they are so easy to solve 0, 1, and 10 are simple of themselves. for the others they are all 2 digit answers the fist digit is the number -1 the second is 10- the number: take 7, 7-1=6, 10-7=3, result is 63. those two things replace memorizing 8. awkward at first and completely confuses most teachers if you show you work but very effective when you get the hang of it.

I always remembered that the two digits for the multiples of 9 added up to 9.

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.

You want to know a trick to know the last digit for any times table entry? Take the complement of each number with 10, and the last digit of the product is the same.

For example: 8 X 6. Difficult, huh? But wait: 2 X 4 = 8. This reminds us that the answer is 48.

Hold out your hands, like you're trying to stop a rapist in Cologne. 9x7? Fold down the second finger on your right hand. Number of fingers on left side of folded finger = left digit. Number of fingers on right side = second digit.

This works for all of them.
