I still think I had more fun than anyone else in this topic, regardless of solving the arithmetic problem or not.
If any one else had more fun, then you are a happier person than I am & please stay that way.
I'm not getting any younger, and some health issues are starting to make some days tougher than others, so I reckon I have to just have some laughs & not worry too much about whether or not I solve arithmetic problems.
I would rather shoot firearms, anyway. Or, read about others having fun shooting.
Thanks, Tom~!
