Directions: Using the digits 1 to 7, at most one time each, place a digit in each circle so that the sum of the numbers in 3 squares (the middle horizontal line or 2 diagonals) are same.

e.g A+B+C or D+B+E or F+B+G

Is there more than one solution?

Be strategic to think about the number in the center circle.

a=7 b=1 c=2

d=6 e=3

f=5 g=4

OMG I didn’t relize that!

A=2 B=7 C=5

D=3. E=4

F=1. G=6
