Are you good at Math? Giveaway inside!

What is that C?

Got the first one, thank you!

uhm. nope :D

Thank you, got second one :)

Nice. I was among the first 3 solvers and couldn't get a key because they were all claimed already. :(

Well I was to slow but thanks anyway was a nice idea :D

Done, thanks and easy :)

In your calculation use only 3 decimal numbers, and don't round the numbers!

You do know that you contradict yourself.. Not using all the digits is rounding.
The correct answer is 4.501581581, which is not the answer you decided on and not any variation of it.

Why'd you use comma instead of a point?

Pfffff.. no pls

If you say" add only 3 decimal numbers, and don't round the numbers!"
people use integercuts...nobody would guess, that we have to round in the calculation but not the result.
It would have been easier if you just say round your result to 3 decimals and also use point an comma in your solution-list.

I kept using points instead of commas! :(

also... i already have the game.

Solved, but have the game already. I might steal your idea, though...it is a cool way to present a giveaway where it requires a bit of effort, you can't google the exact answer, but it is still doable.

solved

All key gone?

ez

I suppose that the real question is: are YOU good at math?

I think not, Mr. Approximation =)

yep, all gone :(
