@Randy Dandy,
Another excellent question Randy Dandy.
Did you by any chance get the book "More Mathematical Puzzles of Sam Loyd" as a Christmas or birthday present?
You mentioned in an earlier post that school was long ago , am I right in thinking that you are interested in math puzzles but sometimes struggle with the method of finding the solutions?
I'm an older person who likes mathematical puzzles, can you tell, lol.
Tell me a bit more about you.
