Using a different numbering scheme in a document's appendix than in the chapters
Applies to:

MathType 6 and later for Windows
MathType 6 and later for Mac 
Microsoft Word for Windows & Mac
(except Word 2008 and 2016 for Mac) 
Situation:
You're writing your thesis and are using MathType's equation numbering. You
want the equation numbers and references to include the chapter number. Your chapter
numbers are sequential numerals from 1 to 68 except for the appendices, which are upper case
alphabet characters. MathType's numbering does not allow you to change from
Chapter 68 to Appendix A for the equation numbering.
Background:
MathType's equation numbering uses Word's "fields" to automatically update
the numbers and references when equation numbers are added. MathType provides an
"Update" button to update the numbers and references when individual equation
numbers are deleted. You can format these numbers according to your needs:
Setting up the numbering for the document
Since you want chapter numbers in your thesis, we'll click to select the Chapter
Number box and likewise deselect Section Number:
Pretty straightforward. When you insert your first numbered equation you'll
see a dialog like this:
Since our document doesn't have any equations in Chapter 1,
we're starting ours with Chapter 2. Set yours to whatever the document requires.
We don't have numbered sections in our document, so it doesn't matter what
number is in the section number box (yet).
At the beginning of each chapter (or if not at the beginning,
certainly before the first numbered equation), insert a chapter break:
Note that the document's chapter breaks and the equation
chapter breaks do not have to occur at the exact same point. It is important
though, to insert a new chapter break even if the chapter does not have
any equations. If you forget to do this, it's OK. Just go back to a
point in the chapter you missed, and add a break there.
Now we're at the Appendix
To change the equation number formatting in the Appendix, you can
wait until the Appendix is complete, but you don’t have to. All you need is to
have at least one numbered equation. However many equations you have in the
Appendix though, select them all. Your selection should cover all equations and
equation numbers in the Appendix, and all text inbetween. (Remember, the
numbers will currently be numbered according to the next chapter in sequence. In
the case of our example, the final chapter was 68, so the first equation in the
Appendix should be (69.1). Don't forget to add the chapter break.)
It will look something like this:
After you make the selection, go back to Format Equation Numbers and choose
to number with NO chapter number, and ONLY section and equation numbers. Set the
Section Number format to A, B, C. Also set it to use this
format for "new equation numbers" and "current selection":
At this point, you've got your document set up the way you
want it. You can even add a second appendix  Appendix B  and equations and
references at any point in the document.
