The company style guide calls for a comma in numbers with five or more
digits. I know this rule doesn't apply to page numbers, but what about
numbers substituted for variables in show-your-work examples:

A = (43,560)(160) = 6,969,600 ft^2 or A = (43560)(160) = 6969600 ft^2

The latter looks so dense! I know we don't use the scientific style of
spacing between groups of three digits in long numbers.
