### Brain Teasers

# Quocorrian Math 2

Math
Math brain teasers require computations to solve.

After being intrigued by Quocorria's mathematical systems, you decide to extend your stay on this mathematically advanced planet.

While talking to a Quocorrian professor, he mentions Quocorria's other numbering systems. Your curiosity gets the best of you, so you decide you won't leave Quocorria until you master all of their systems.

The professor gives you a piece of paper with four true math problems on it. Like before, you must discover the system.

Note: This is a different system than last time

Here are the problems:

2+2=12

5-3=62

3x4=61

6/3=83

So, using this system, what is 1-3?

### Hint

Again, this is not an actual number system (decimal, binary, hexadecimal) but a variation on the way we do math.### Answer

18.In this system, you multiply each number by -1, changing it to its opposite. Then, do the operation normally. Then, add the two numbers together and square it. Add that to the original.

For all you equation people...

-a*-b+(a+b)^2

With the * being the indicated operation.
