    According to Wikipedia, "in mathematical logic and computer science the symbol has taken the name turnstile because of its resemblance to a typical turnstile if viewed from above. It is also referred to as tee and is often read as "yields" or "proves"." The symbol itself looks like a letter t on its side, similar to a left-pointing, straight arrowhead (sec. 158) Would it be possible to use that arrow symbol (with a short one-cell shaft) to represent your symbol? You would have to define its use, of course.

    In a Nemeth transcription, everything is transcribed according to the Nemeth Code, including the glossary. According to Rule XVIII §120, the grouping symbols of English Braille must never be used except to enclose literary material on title pages. If a grouping sign occurs which is not listed, the transcrbier must devise a symbol whose first component is 12356 for opening and 23456 for closing. Those devised symbols would go on the Special Symbols page (and probably a tn at their first occurence).

    g and mol are abbreviations so the g would require the letter indicator. In Chemistry Code, letters and abbreviations are both punctuated mathematically, so you would use a punctuation indicator before the semicolon that follows g/mol.

    I tried brailling the cancelled column and row in the matrix as you suggested. I'm not sure that clearly represents what is shown. The cancelled top horizontal row would have inside it another cancellation indicator for the first item in the cancelled column. Would it be clearer to insert a tn stating that the top row and middle column are cancelled in print? or that there is a line drawn through the column and row?

    As far as using cancellation symbols in the horizontal row, I don't believe the spaces would end the effect of the indicator.

    I apologize for the delay in responding to your question. I have been out of town and neglected to get someone to fill in for me.

    I don't know what your absolute value symbol looks like in print. Usually absolute value is indicated by vertical bars enclosing the number or letter. In that case you would use the braille vertical bar (1256) If your symbol is something other than a vertical bar, please let me know.

    Hi Francine,

    This new forum is not yet fully functional and if you can "Click here to view past topics" that will take you to the old forum, which is still working. However, I'll try to answer here. Is this book in English with just these Dutch names? It it's English that just happens to have a Dutch name, see EBAE for handling foreign language words and names that are present in English. In this case use contractions including the ED in Smedestraat. English braille rules apply, not foreign language. Of course, it depends on on what kind of book this is. I'll look forward to your reply, I do suggest that you try the old forum, however, but I'll take a look here too. I really need to know that in order to give an accurate answer.

    This is for a college logic class. Never heard of it before. Thanks for checking.

    I'm sorry to admit that I don't know anything about Logic. It's been a long time since my college days. I can quiz other math transcribers about it and find out if anyone knows what a Turnstile math symbol is.
