Awesome - I think I only forgot the punctuation mark before the period - so I was close!  Thank you again!

I have the yellow "An Introduction to Braille Mathematics" and it's wording can be a bit confusing.

Nemeth Code for Mathematics & Science Notation, 1972 Revision.

Is this the manual you are referring too?  I probably need to print it as I prefer searching and making notes in actual print form - not e-form.
