2+2=4
The world is round
the sky is blue
Perhaps the sky isn’t blue to everyone.
2+2=4 unless you are doing modular arithmetic for values less than 4, my friend.
The world is only round for certain definitions of round. It is more accurately described as an imperfect oblate spheroid.
The sky is blue, except when it’s black, pink, orange, red, etc…
You, two, are sure making the OP earns his name.
Here is your cite.
But 2 + 2 = 5 (for extremely large values of 2).
We have this straight from the pen (or from the keyboard, I suppose) of SDSAB arch-Master Dex.
Cite.
But what do you mean by “perhaps” and “everyone”? Could you explain those terms?
anyone following the Shall Issue thread might have spotted the inspiration for this thread
And small values of 5
I recall a discussion on the SDMB about an old book on number theory (or was it logic or set theory?) where the author ***finally ***proves 1 + 1 = 2 on page 78 (or whatever).
Postulation.
If you’re rounding up the answer, shouldn’t you also round up the input, and say 3+3=5? (Unless it’s 2.76 or higher, in which case it’d be the more expected 3+3=6).
Not rounding up, rounding to the closest integer.
No, here you go. If you wanted an actual proof the whole thing is online at the UMichigan website but I’m not digging through it for you.
Isn’t 3 the closest integer to 2.6?
Yabbut, 2.4 doesn’t round up to 3, it rounds down to 2; but 4.8 rounds up to 5.
This whole thread is crimethink. Two plus two is whatever the party says it is.
Well, it all depends on how you define things. Let’s take the following definitions:
2 is defined as 1+1
3 is defined as 2+1
4 is defined as 3+1
Then:
2+2=2+(1+1)=(2+1)+1=3+1=4
Quod erat demonstrandum
That’s nice, and all, but careful reading of the question can save time and effort. The OP didn’t ask for proof. Just a citation.
