[Blindmath] Basic Math

Tue Oct 11 16:22:04 UTC 2016

I am using hard copy Braille on a Perkins, but I also have an abacus 
available, although I am not sure how to set these kinds of problems up 
on an abacus.

> Hi. I'm taking a basic math class online where I don't have an accessible textbook available yet. Unfortunately, since it's been several years since I've taken math like this and I have health issues now that have made it very hard to remember how to do the work, I'm really struggling with learning how to do it. I was wondering if anyone might be able to give me tips on how to handle problems like the ones I'm including below. I have a few friends who are trying to help me, but they're sighted, and without the textbook, I'm finding it difficult to understand what they're telling me. They do these problems in a very visual way, so I know they're having a hard time, too. Here are a few examples of problems I'm working on.
