Very clever - this conundrum has been around for years and the answer is always 9 - don’t know how or why.
That is brilliant;)
Yes. It’s been around for years. I’m just old and forget things like how funny an old joke is until I re-hear it. Lay it out in an excel spreadsheet and you’ll see the pattern. 9-times table from 2nd grade if you went to Cathloic School, if you went to public school 10th grade.
