The following puzzle was sent from Richard Feynman (Nobel Prize 1965 in Physics") to his mother in a letter. The puzzle was for his father. The puzzle was not original with Feynman. He got it from an 1936 article in American Mathematical Monthly. "A" represents the same number where ever "A" appears. The dots can be any number but "A". All you need are basic math skills and understanding like addition, multiplication, long division, and subtraction. Who can get the answer first? Have fun!!
