Problem of the Month

Geometry Cross Sum



Using only the digits 0, 1, 2, 3, 5, and 9, can you make each of the ten diagonal rows in the triangle add up to the same number?

Here's the catch: Each area with the same letter must also contain the same number.




Solution to the Problem:

G = 1
E = 2
O = 3
M = 0
T = 5
R = 9
SUM = 14



I guess we must give James Alarie extra credit for his answer:

'You said, "Each area with the same letter must also contain the same number." You did NOT say, "Each letter must be a UNIQUE number."

This omission allows three solutions:

G=0 E=0 O=0 M=0 T=0 R=0 SUM=0
G=0 E=0 O=1 M=1 T=1 R=2 SUM=3
G=1 E=2 O=3 M=0 T=5 R=9 SUM=14'
