[Blindmath] Math in your head (was: alternative methods of learning college algebra)

[Sean Whalen]

But math is not visual, people just generally elect to represent concepts
visually. A numerator above a denominator with a line separating them is
nothing more than a way to represent dividing the one by the other. I know
you know this. But what is really important is understanding the concepts. A
bell curve is a visual representation of the normal distribution. Yes, I can
tell you what the curve looks like because I needed to learn to communicate
with the vast majority of folks who use that representation, but I could
explain the distribution in terms that made no reference to the curve
commonly used to represent it. Not being able to rely on those visual
representations has, for me, actually allowed, and sometimes forced, me to
really grapple with underlying concepts.

Hi all,

I suspect one reason that people think math is visual is because of the
special way it is written. Take fractions as a basic example you write the
numerator in one line, then draw a line below that and then below that line,
write the denominator.
