Thank you, I was (of course) looking for the base10 answers since I would have stated if I would have needed another base.. (tip: Since you where given the answers in many bases, I would not have skipped base2. (that is of course 100) . since thats actually used.. don't know where base3 and 4 are used in "real life"?!) Again, thank you fer letting me pay for this question. I just made $20 from a bet... better share something with you ;) thanks thanks thanks :)

Google doesn't admit new researchers so I can't answer but can comment: x is the right side of the equation. You could also say that x is the unknown. Is that enough or you want also the value of x?

Hey Nediam, There is a suspicion in the GA community that persons who post this kind of question are just testing the validity of stolen credit cards. Of course (!) you're not, are you? Myoarin

Myoarin, Of course I'm not!! (then I would not need anyone to answer my question... since I'm charged $0.5 just for posting the question.. which would be enough for validation of a credit card) I was not gonna say it here.. since it spoils my fun a bit... but...the reason... I want to be the guy how payed for knowing what 2+2 is... could be a word record or something!! :p But if nobody wants my money I can close this question.

I believe you! Sorry, I should have checked for your other questions. Omnivorousga is the only commenter till now who is a GA Researcher, who could post an official answer. He has also demonstrated greater depth in his approach. I keep thinking there must be a potential joke at the expense of the present US adminstration that could be based on your question. Cheers, Myoarin

I am reminded of an old, old joke. I first saw this scrawled as a graffito in the ladies' room of the math & science building of a university: 2 + 2 = 5 (for large enough values of 2)

I hate to disagree with the answer, but there is only *one* result, and that is 4 (or 4<base10> if you want to be pedantic), since x = 4<base10> = 11<base3> = 10<base4> = 4<basen> for any n>=5 (where digit 4 is valid) That is, the *result* does not change only the *representation* of the result changes if you switch the number system. All representations though are equal, and all refer to the same number. Regarding usage of these bases apparently base3 (called ternary) has some use in Islam, while base4 (called quaternary) seems to have no practical use, although it has some interesing connections with binary (like octal and hexadecimal do, which motivates the use of these systems) For details check http://en.wikipedia.org/wiki/Ternary_numeral_system and http://en.wikipedia.org/wiki/Quaternary_numeral_system ... and all that coming out of the question of how much is 2+2!

One could argue that 2 + 2 written as ((2^.5)^2) + ((2^.5)^2) <= 3.9999 etc using the rules of BEDMAS we first solve 2^.5 which is irrational. If we square this irrational number we will never get back to 2, in fact we will only get 1.9999 etc. Of course this is just a mathematical abstraction.
