### Brain Teasers

# Quocorrian Math 3

Math
Math brain teasers require computations to solve.

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?

### Hint

This system is not commutative. 3+2 is not the same as 2+3.The Order of Operations is the same as our own.

1+1=5.5

### Answer

90.In this system, you multiply the rightmost number by 1, the second rightmost number by 10, the third by 100, and so on. Solve the problem like that, and divide by two.

So 2+2 would look like (20+2)/2.

4+3*5-6 would look like (4000+300*50-6)/2
