That's Really Sum-Thing
by Sidney Kravitz in GAMES

Can you fill in the diagram with the numbers 1 through 6 so that each number appears exactly once in each row and in each column?

The clues tell the sum of the numbers in certain squares.
For example, the first clue A456 = 14 tells you that A4, A5, and A6 add up to 14.

It's helpful to remember that the sum total for each row and column must be 21 (1 + 2 + 3 +4 + 5 + 6).

Clues:
A456 = 14
B45 = 9
BC2 = 4
C345 = 8
CDE4 = 13
CDE6 = 8
D345 = 8
DEF3 = 6
E12 = 9
