[Blindmath] alternative methods of learning college algebra

Mon Dec 14 17:34:41 UTC 2015

Remember the math behind airplanes and the early space program was all done
with a slide rule. 
I once found a bug in a calculator because I knew how to do math. 
Just something to keep in mind.

Though I can understand your perspective as a blind person, just about every
human being in the modern world carries a cell phone, and all cell phones
have calculators. Why trust or tax your memory when a device which can
compute far, far more than your brain will ever be able to calculate is
right in your pocket. Why walk across the country when a technological
advancement such as an airplane will take you to your destination in hours
with no effort on your part. 

Those who know math well such as professors and opt to make calculations
using paper and pencil are probably doing so because they have long become
aware of the human brain's computational weaknesses and simply solve
problems in this way to eliminate the possibility of error. 

The reason we as humans have seen an incredible jump in our technological
advancements is due to computers. If we didn't invent computing machines we
would be stuck using slide rulers and taking all day to compute relatively
simple calculations which would overall hinder technological advancements. 

I can imagine making calculations in your head gets some "wows" from others,
but it is not reliable if your goal is accuracy. One will have to weigh the
pros and cons of learning and practicing mental math over the amount of time
necessary to learn such a skill. 

If you want to see some amazing stuff, look up videos with Asians competing
against one another using the abacus. These guys are multiplying and
dividing 6-digit numbers in seconds, which would not normally be possible
without such an instrument.

I would hesitate to say that you absolutely have to learn braille math. 
But I'd be even more hesitant to say you don't need it either and I would
put a different spin on doing everything in your head. Being able to do math
in your head is an extremely valuable skill to have -- if you can develop
it. That's actually true for any math student. Personally, it amazes me how
some really good mathematicians have to write everything down. It strikes me
as primitive. But I'm sure humans vary greatly on their ability to do math
in their head and some people are going to have a greater need to write
things down than others. It strikes me as bad advice to tell someone to
forget about writing stuff down.

I do like the advice someone gave to learn latex. A knowledge of latex is
considered so basic here at the Department of Mathematics at the University
of Wisconsin that we don't even teach a mini-course in it any more.  We
don't teach the alphabet either. If you are going to major in math, you're
expected to know latex.
