    Can one solve this mathematically i.e. not by trial and error? In 1988 my granny was quite a bit older than my grandpa. The difference between the square of their ages was 1988. How old were they?

    Crypto-Anagram #2

    You got it! Crypto Rodent whittling professionally (not really "professionally" as the result seen in the picture!) Rolling Stones ... (Don't) Play With Fire (added the "don't" to make a meaningful anagram!)

    Cutting pizza

    Vertical (in any direction) = straight down. Horizontal as in figure, e.g. a cake. Two vertical cuts give 4 pieces, then the 3rd cut (horizontal ) divides those 4 pieces into two each for a total of 8. Horizontal cuts are therefore excluded.
