Fill in 123456 in o to form a triangle. Every three numbers add up to 10

123456 these six numbers, the first two numbers add up to the last three numbers how to calculate

12+3=4+5+6

Put 123456 in the six circles. The sum of the four numbers at the vertex of each square is 13

[2]----[1] [3]
[6] [4] [5]
2 + 1 + 6 + 4 = 13 on the left and 1 + 3 + 4 + 5 = 13 on the right
