This tip might help some people. I had difficulty learning the times-tables and addition of larger numbers. Then I was given a dart board for my birthday and I quickly learned multiplication by threes and addition of the dart board numbers and tallying of my scores. It wasn't that big a step to learn the rest of the times-tables. The rules and scoring of darts can be easily changed in order to make learning all of the times-tables fun.
Nowadays there are harmless Velcro dart board games that younger children can play. I still have guilty feelings about the time I threw a dart 'near' my sister and it landed in her leg.
Hope this helps someone.
Hi Fred Smith;
Welcome to the forum Fred.
In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
