Spacing between degrees symbol and capital letter

[Chris Clemens]

Please see the attached examples related to our question. We have a 5th grade math book with a section discussing integers. Included in the lesson are examples where a number is followed by the "degrees" symbol and the capital letter abbreviation for Fahrenheit or Celsius.
Please consider the examples and whether or not a space should be left between the symbol and capital letter (Rule VIII-Section 54b), or should there be a return to base line indicator with no space (Rule XXII-Section 165)?

We appreciate the opportunity to pose this question and look forward to your reply.

When written with a number the degree symbol is interpreted to apply to the number. The following letter (F or C) is an abbreviation and must be separated from the number (and degree sign) by a space. The letter is then punctuated in literary mode as an abbreviation. If there is no number, the degree sign applies to the letter. A dot 5 brings the braille back to the baseline and the expression is punctuated in mathematical mode. Did I just confuse the issue? Hope not.
