Ok, I'll delete the colon, but I'm including a TN prior to the first instance that says:
In Print below, the unit numbers inside the brackets are subscript in small capital font. Also a braille arrow (symbol shown) is used for a double arrow in print.
Is it permissible to add a space between the word UNIT and the following number (UNIT 1 instead of UNIT1)? Because otherwise the student will read UNITABLEA.
