[BlindMath] Reading wiki page containing formula

[Neil Soiffer]

Chris,

I implemented both MathPlayer and MathCAT (which is a replacement for the
end-of-life MathPlayer). There are some bugs in some of the synthesizers.
If you are using a oneCore voice, it doesn't support the command to force
the long "a" sound instead of the short "a" sound. I found a work around
and that is part of MathCAT, but I can't do anything about MathPlayer to
fix it.

You should be able to navigate any expression by hitting enter when you
move to a math expression. There is a list of navigation commands supported
by both MathPlayer and MathCAT
<https://nsoiffer.github.io/MathCAT/nav-commands.html>, but the arrow keys
are pretty intuitive and do most of what you likely want. For tables, use
cntrl+arrow to move among the cells.

As to your question about "r" and "q"."r" is the remainder and "q" is the
quotient (the integer part after dividing). Starting with n=13 and k=5,
13/5 gives 2 with remainder 3. You may want to read about the Euclidean
Algorithm <https://en.wikipedia.org/wiki/Euclidean_algorithm>to better
understand the page you referenced.

Good luck,

    Neil
