Nines are easy. Up to 9 × 9 (only using integers) you can use this system: subtract 1 from whatever number your multiplying 9 by and that will give you your first digit. Then take whatever number needs to be added to the first digit to sum to 9, and that is your second digit. Ex: 9 × 7 and 7 – 1 = 6 and 9 – 6 = 3 so then 9 × 7 = 63! After that, 10 x anything is easy, and so is 11 time any integer below 11. Just remember that 12 × 9 is 108 and you good!
Every day, back in elementary school, we went over and over the times tables, reciting them aloud. It didn’t hurt us at the time and has stood us in good stead for more than seventy years!
Another way I learned was to bring out both of your hands, and put down the other number’s finger(ex: 7×9 is put down your seventh finger) and then count all the first fingers before your number(ex: 7 is first 6 fingers) and the number is the tens digit. Then you count all the numbers from the other side(ex: 7 is 3)Now put that number as the ones place. This only works for 1 to 10 though. Make sure to not count the other number, just use it as a barrier. After practice, you will be able to do it fast, and then, the next week, YOU MEMORIZED IT!!

Like he’d be able to keep that kind of promise to the end of the school day.

Kevin should watch Schoolhouse Rock. That’s how I learned my multiplication tables.

I didn’t realize Jack Benny was an elementary school teacher in the ’80’s.
