wait a little and I’ll show you how not to be concerned with 63 of the products you have to learn up to 100 so you’ll only have to become familiar with 37, but I hope you don’t just ‘learn your tables’ without thought, that’s antiquated..here’s two quick tips to be going on with when you are considering two factors to be multiplied together:
don’t learn both forms, learn one
learn the one in which the smallest number comes first
e.g. 6×8, 8×6
forget the 8×6
that’s halved the problem nicht wahr?
slight problem: you’ll really have to work on the flip law until it’s second nature
