Dorothy, thanks again for your help. I have another question on the same topic. I've just received the next workbook in the same series as previously discussed. 8th grade, with no accompanying textbook, so I can only go by context of each page in the workbook. In this next workbook in the series, the first page shows a number line with the same raised minus sign to look like a superscript. But it is obviously a minus. Now I think this publisher is printing all the minus signs in a raised position. I have attached the page with the number line.

I have already sent the 1st workbook out with the raised minus signs transcribed as superscripts. I am really frustrated and I know the student will be confused. Please give me you best advice on how to proceed.
