### Brain Teasers

# Quocorrian Math 1

Math
Math brain teasers require computations to solve.

While on your interplanetary vacation, you decide to stop at the planet Quocorri, a planet known for its many mathematical achievements.

While there, you decide to pick up on some of the Quocorrians mathematical variations. The Quocorrians won't tell you exactly how it works, only that it has some relationship to the Standard English math. They also give you four, true, Quocorrian math problems. They are:

2+2=9

4*1=1

5-2=16

-3+2=64

So, according to this system, what is 6/2?

### Hint

The system is not a number system (decimal, binary, hexadecimal...), but a variation of the way we do math.### Answer

81.In this system of Quocorrian math, you change the operation to its opposite (+ to -, * to / and vice versa), and solve regularly. Then, you subtract three from that answer. Finally, you square that to get your answer.

Good one

are all of those smileys really necessary

yes, to show my pleasure with it.

wow, that is complicated

I do not appreciate that feeble attempt at humor, or whatever it may be in the comments of my teaser. Please restrain your immaturity, folks

-3+2 should be (+3-2-3)^2=4?

We don't appreciate the feeble attempt at a teaser. You can introduce all kinds of complexity, but if there's not a reasonable expectation to be able to solve it with some math skills, it's rather pointless.

interesting...i'm completely flummoxed by this one...(or was until I read the answer! :lol

Wow that was hard. How hard was it to make this?

I didn't find that too hard or too easy. The first thing I noticed before even looking at the problem was that all of the solutions were perfect squares. I then took the square roots of each of them and attempted to find a half decent solution that worked for all of them.

Good puzzle.

Good puzzle.
