One remembers many trivial arithmetical facts: the sums and products
of various small integers, the small primes, etc. I discovered today
that the first multiple of three that I do not remember is 3x26. How
far up the three times table do you remember?

In true monty python-esque form, I fall over at eighteen
threes. Eighteen threes is always fifty-six, no fifty-four,
aaaargh! <fx: jetisoned into a chasm />

I never thought about a "three times table", as the multiplication of 3
times any 2-digit number takes place in one's mind so rapidly that it
is not possible (for me, anyway) to say whether I'm actually doing the
multiplication or whether I'm just recalling the result from having
done it before and "remembered" it. It's an interesting question, at
any rate.

Grover Hughes
