Your explanation of 9x and 11x would blow the mind of many an A-Level student these days, they wouldn't even know what you meant. As you say "basic maths understanding" of how numbers work but too many simply rely on computer aided maths now-a-days. Good luck with it fella, don't envy you one little bit having to teach one of your own, stress levels through the roof I'd bet.So true, the multiplication divisions taught at infant school in my day set you up for life. They were chanted by all the kids in unison up to the 12 x tables, unsure why they stopped at that. Little tricks also, like for 11 x, do 10 x and add a tenth or nine x and knock off a tenth. Great basic maths understanding, guess it's not been that way for a long time.
