[Blindmath] Stat Formulas

[cnsbaker at access.k12.wv.us]

Regarding .brf files that I have produced for the student I work with (or have let them create) the symbols on the screen look like simulated braille or in some cases they are ASCII code, or as we say where I work, computer braille.

Simulated braille looks like braille only it shows all the dots. The dots within a cell that would be read are bolder, or more pronounced, then the other dots that you would not read, (the ones you don't remind me of weak dots).

ASCII  or computer braille is the symbols used on the keyboard to produce the desired braille sign. For example, to produce the braille sign to indicate greater than or equal to you would use the keyboard keys shift and quote, then the letter key k, then the shift and semi-colon key. 

On the computer screen you would either see dot 5, dots 4-6, dots 1-5-6 or you would see quotation, k, colon, depending on how you have your program set or how it's default settings are set.

Hope this helps and didn't further confuse you.
