Will one of you nerds explain this plz
12x12=144
144+12=156
the number is the number of interceptions.
>>28335714
intersections**
>>28335659
The times they intersect.
Red & Green = 1
Red & Black * 2 + Green & Blue * 3 = 5
...
Oh gotcha thanks
>>28335659
use the colors, the red and green intersection represents 100, of the group of 5 each represents 10, and of the blueXblue intersections each represents one
or you could just do
13x12 = (10+3)x(10+2) = 100 + (3+2)x10 + 6
