Reply To: Number before Function
Print copy often spaces terms and symbols in an equation or expression. In braille we follow Nemeth Code spacing rules. Do not space between the numeral and the function name or abbreviated function name which follows.
A space is required following the function name/abbreviation and its modifications, if any, as explained and illustrated in the Nemeth Codebook, Sec.119.
