Hmm, are you saying that you learnt to do algebra _before_ using plain
numbers?

All I'm trying to get across is that there's probably a good reason why
we tech kids that to calculate

 (4*3+2)*2

you first calculate 4*3, then add 2, then multiply the lot by 2.  Each
step would be written to paper until the kid learns to do calculations
like this "in RAM".

I'm suspecting this manner of teaching has foundation in pedagogy.
