July 2014 - Hint 3

In the KenKen puzzle: the 75x in the upper left corner must be 3x5x5; since no row or column may repeat a number, the 3 must go in the corner. The 20x in the lower corner must be 4x5 (in either order), which forces the locations of the 3 and 5 in the 15x cage above it. This leaves 1, 2, and 6 for the upper three squares in the last column, so the 1- at the top must be 2-1 (in either order).
