The trick that I teach the shorter humanoids is to subtract 1 from the multiplier of 9, put that number in the 10s column, then complete the nine and put that in the 1s column.
Then we spent some time finding the pairs of numbers that make 9. 1+8. 2+7, 3+…7+2, 8+1. I have to be explicit in this part, or they will shortcut to 3, (use fingers to count to 9) uh 6?
They usually learn it in a day or two. To get them to flash to instantly know their times tables takes longer.
Same energy as multiplication with 9, just take 1 from the right side and put it on the left
(09, 18, 27, 36, 45)
Instructions unclear…
09, 108, 1107, 11106, 111105
Keep doing this until you get a binary number and then your pc can do the rest for you

4 5 therefore 9
9 and 9 therefore 18
18 and 18 therefore 36
4 5 therefore 9
