math formula with concrete number as a result

Hi, can someone help me? I would need a really challenging math forumula/s with end results 6 and 11. Anyone? pls

The end result numbers are supposed to be a hint.

Thank you.
p.s. It really needs to be a proper brain teaser, something really difficult.

(x-6)(x-11)=0

Wonder what he means: "challenging formula" ?

challenging formula means something that is quite a challenge to solve. we are not talking "secondary school math" here.
e.g. not 16 - 10 = 6
I want a tough mathematic exercise with end result/s 6 and 11 (could also be 6.11 or 11.6)

as I am absolutely lost in math, hence I'm looking for help.

The result will be then a hint for something else.

Thx

Why in the world would "16- 10= 6" be "secondary school math"? That looks like third or fourth grade to me. The problem mathman suggested, to solve $\displaystyle x^2- 17x+ 66= 0$ might be "secondary school math".

Are you looking for something NOT really mathematical,
but more a "trick" (since you mention "puzzle") ??

Can you get someone to help you post your problem;
as is, it is unclear...and keeps being unclear!

Well, ok, fair enough, the example I provided is "primary school" one, but I only wanted to exaggerate that it can not be easy.

I can't explain it in any other way then - mathematical exercise, mathematical formula to solve, to count, where end result will be number 6 and 11. it can be 6.11 or 11.6 or two formulas / exercises.

It is aimed for math university graduate. (masters) so it needs to match a certain level of difficulty.

The end result is then hint for something else.

If a problem is set up using (as example) speed, distance and time,
such that the answer is the time at which a certain distance is
travelled, and this time is 6.11 a.m. (meaning clock time);
is that what you're after?

Ok, I'm lost and I give up.
I am not "math person" and I think this is just two different worlds.

The answer does not need to symbol any time, distance.. or anything... just plain number 6 and 11. They can be two examples.

In other words, this: x² − 17x + 66 = 0, but 1000 times harder.
