This continues from Math tapestry puzzle #1. Find the rules there.
Continuing on from that, I saw my friend Jason come outside. We had a conversation about the things that are here. Suddenly he says: "Wait! I have to show you something." He shows me this:
NN 07
44 aa 32 39
bb 22
36 31
dd 28 cc 11
27 33
He says he made it, but he's not done yet, although the highest number he's planning to use is 44. He doesn't know what number belongs there. Can you help him?
