How do I work the hidden_resource EDB system?

[TWFanatic]

y1 n2 n4 n8 is a binary number and also needs the region in question to uniquely identify a province.

NW region, province number 0001b (= 1d) in this instance, where b means binary number and d means decimal number.
n1 y2 n4 y8 means 1010b = 10d.

y1 n2 n4 n8 => YES, there is a 1; NO, there is no 2; NO, there is no 4; NO, there is no 8. In other words, only 1 and therefore 1.

n1 y2 n4 y8 => NO, there is no 1; YES, there is a 2; NO, there is no 4; YES, there is a 8. In other words, 2 and 8, and therefore 10.
