Wow, you mean there’s really people who didn’t figure out this pattern on their own in the third grade?
Just wow.

There’s also the fingers trick… put down the finger of the number (1-10) that you’re multiplying by and the remaining numbers make up the answer.

Example (In case your teacher never taught you this either):

4 x 9

Look at your palms, face up
Put down your left ring finger
3 finger left on the left side, 6 on the right
The answer = 36

Another thing unique about 9:
18 1+8=9
27 2+7=9
36 3+6=9
45 4+5=9
54 5+4=9
63 6+3=9
72 7+2=9
81 8+1=9
90 9+0=9

yup and it works with any number multiplied by 9. You just keep adding until you get back to 9. For example: 179 x 9 = 1611 -> 1+6+1+1 = 9, 2397 x 9 = 21573 -> 2+1+5+7+3 = 18 -> 1+8=9.

I knew someone who said that the number 9 is the only perfect number because it is the only number you can do this with.

Now, let’s do it with 8’s

that was the only way I got through the 9s in elementary school!

My teachers never showed us any of these. I had to learn my times tables the old fashioned way.
