University Press, 1954, says that mathematics should be punctuated as <br>
normal text. For instance, if a formula is at the end of a sentence then <br>
it should be followed by a full stop (period).<br>
<br>
"Mathematics into Type" by Ellen Swanson, American Mathematical Society, <br>
1999, shows many examples of punctuating math with commas and periods.<br>
