Hi John, It is a good idea to read again The TeXBook, but actually I wonder why should TeX put a horizontal line between 1 and 2 in your code? What you are typesetting in mathmode is just 8 followed by 1 in exponent (uppserscript) and 2 in subscript, therefore there shouldn’t be any fraction bar between 1 and 2. If the font you use has the character, what you want to typeset is the character U+00BD for 1/2 or, if you want to use mathmode, either of the solutions below (wtach the slight differences between the three versions): \starttext $8\tfrac{1}{2} × 11$ inch $8\frac{1}{2} × 11$ inch $8{1 \over 2} × 11$ inch \stoptext Indeed you can replace $…$ with \math{…}. Best regards: OK
