Hi Robert,
I'm a retired middle school math teacher and I gave my students a similar problem so I was familiar with a problem like this. The problem was "what times on a digital clock show digits whose product is 75 ? " The digits could be combined as one number
also. Some answers would be 5:53, 3:55, 5:35, 5:15 (5*15), etc.
Have a good day.

my question is, how many times in a 12 hour period does the sum of the digits shown add up to 13?
