It will turn more towards thinking skills and problem solving skills. That's why I'm not too strict with the multiplication tables. I never myself learned them all to 12 (:o) but with practice, I came to know the tables on the tip of my fingers. I came to even know the tables of 13, 15, 16, 25 especially.
I've tutored enough math, and believe that knowing the times tables sure goes a long ways towards doing algebra, geometry, trig, etc. I always refused to allow my grade school and high school students have calculators until I was sure they knew the times tables and knew how to think through the various math problems.Quote:

In the same way, my mom had me and my siblings learn how to properly mop a tile floor on our hands and knees, so we'd understand how dirty the corner can get and where the fallen crumbs like to hide.

I think I'll include:
Algebra (solving, simplifying, factorising)
Trigonometry (solving, simplifying, identities)
Probability (conditional, independent)
Coordinate geometry (plotting, drawing lines, curves, gradients, trigo curves, area, volume, three dimensional coordinate geometry)
Linear law
Rates
Functions
Indices/Logarithm
Partial fractions
etc
That sounds like a very helpful thing to post.Quote:

You apply your knowledge of multiplications to solve more complex problems. The world does not need a population of reciting parrots, but a thinking, innovative population which can take the best decisions.
It is in this respect that I'm directing my point.
I understand what you're saying, but if I had to solve 257 x 911, I'd jot it down on a piece of paper (keeping my columns nice and straight) and solve it forthwith, rather than dig around in the junk drawer for a calculator.Quote:

One mistake in a calculation, and the answer would be wrong (and we'd get a lower grade).
Another thread...
This one is about whether a person is too old to learn math.
I'll unsubscribe then.Quote:

And for the random number I said earlier, I would have 'improvised' because of the presence of the '11'.
Apart from that, I can say I don't have a 'super' memory, but I memorise things easily with practice. After so many multiplications, how can I not know the basic tables? :)
Oh, speaking of calculation mistakes, the exams we have now deduce little marks for such mistakes and they still give you marks for the working, your methodology to tackle the problem.

I think we are hi-jacking Clough's thread :eek:
At least this OLD PERSON (me) is talking about math like she can do it, and we're not talking about Alty's bunnies and hheath's kittens.Quote:

Yes, see you on another thread WG :) Have a good sleep!
