Bound by your promise to stay on Quocorria until you've mastered all of their numbering systems, you find yourself still stuck on Quocorria.

Now, while attending a Quocorrian mathematical seminar, the speaker mentions yet another form of math. After the speech, you approach him with questions on this system. Being like the rest of the Quocorrians you've met, he only gives you a sheet of paper, this time with six problems on it, and leaves.

Here's the paper:
2+2=11
6-4=28
4*5=100
10/5=10
3-4=13
4+3*5-6=9497

So, knowing that those are all true, what's 3*6?
