[Blindmath] advanced nemeth questions.

[Rasmussen, Lloyd]

Thanks for posting that.
Window-Eyes 8.4 pronounces these special characters correctly if you go over them a character or a word at a time. If you run a braille display and activate UEB with contracted braille on, these render, I think correctly, in UEB.

There exists is a two-cell symbol: dot 4 followed by dots 1,2,3,4,5,6 (dot 4, full cell).  ∃ For all is another two-cell symbol: dot 4, followed by dots 1,2,3,4,6 (dot
4, and).        ∀
Therefore is a two-cell symbol: dot 6, followed by dots 1,6 (looks very much like the print version) - this is different from what was stated earlier.  ∴
Such that was stated correctly before: dots 1,2,5,6.    |

I agree with Sarah that the only thing I can think of would be "element of" for "in" or dot 4, followed by dots 1,5. However, if you could forward us a "print" version of the symbol I could verify that more easily.

Many symbols can actually be copied and pasted and stay intact with the right software installed. I've illustrated this after each symbol above if it made it through on your computer. My screen reader won't read the print symbol though!! <grin> So this is only for readers with enough vision to see it.

I think "in" would be "element of" which is 4,1-5. (an e preceded by a dot 4).

How would I write these symbols in nemeth?
forall,
in
suchthat
there exists
therefore

An example, even though it is kind of pointless.
Forall x in [1,2,3,...,n] there exists a c such that [c*1,c*2,...,c*n] = [1,2,...,n] therefore c = 1.
Thanks,
Derek
