Solution to #59:
You ought to be correct, JaneFairfax and John E Franklin!
But I had the series of side total of a magic square, commencing with a 3x3 magic square using number 1-9, in my mind!

Solution to #63:
Well done, mathsyperson!

#64. A snail creeps 9 ft up a wall during the daytime. After all the labor it does throughout the day, it stops to rest a while... but falls asleep!! The next morning it wakes up and discovers that it has slipped down 6 ft while sleeping.

If this happens every day, how many days will the snail take to reach the top of a wall 63 ft in height?
