1+1 =? What do you think?

if we are talking mathematics then it is 2\nif we like to manipulate with words then it is 11\nif we are talking about a man and a woman then 1+1=1 (or maybe more in case of twins)

I think you left something out. If it is the sum of you must have two things to add. If it is the sum of 7 AND a number it would be \n7+x

No, it follows from 1+1 = 2\n\nWhich follows from 1+0 = 1\n\nBut that can be considered an amazing "fact".  In reality, it's an axiom - a definition.  One of the only true defintions that form the basis of mathematics.

hello!!!!!!!!!! \n1+1 in binary is 10! it's not ten but one zero!!!

Is it twice the "same number + 3"\nor\ntwice the "same number", + 3?\n\nCase 1:\n5(x - 1) = 2(x + 3)\n5x - 5 = 2x + 6\n3x = 11\nx = 11/3\n\nCase 2:\n5(x - 1)  = 2x + 3\n5x - 5 = 2x + 3\n3x = 8\nx = 8/3\n\nThe phrasing can be interpreted either way, so the problem is ambiguous, but I would go with number 2, that seems more intuitive to me.

I think, therefore I am.\n\nAssume 1 does not exist.\n\nLet x = 0\nLet y = 2\n\nAny pair of numbers have a number between them, known as the arithmetic mean.\n\nTake the arithmetic mean of x and y:\n(x + y)/2 = (0 + 2)/2 = 1\n\nBut we now have a result of a number that shouldn't exist.\n\nSince we have a contradiction, this proves that our initial assumption was incorrect.\n\nTherefore 1 exists -- proof by contradiction.

The sum of (-1)^n from 0 to infinite...1-1+1-1+1-1....\nGrouping this sum like this first: (1-1)+(1-1)+(1-1)...=0+0+0+...=0\nOR Use the following grouping: 1+(-1+1)+(-1+1)+...=1+0+0+0...=1\n\nThis is a fun problem, and shows that when using summation, be careful.

You are thinking of the book 'Principia Mathematica' by (Bertrand) Russell and Whitehead, written in 1913. The book was actually dedicated to putting mathematics on a logical foundation. It uses rather antiquated notation and really didn't accomplish what it intended to do, but it was a massive effort. The statement that 1+1=2 came in the middle of the second volume of the three volume set. There is a paperback version for about the first half of the first volume that is still available.

If you add the numbers together then they equal an even number.   1 1  1+1=2

LOL\n\nI can follow you up to n+1=2, what's 2n?\n\nn+1=2  so  n=2-1  so  n=1  so  2n=2

1\nbecause one times one is one.

More universe.\n\nWhat's the greatest number you can count to plus one?

Because it's incredibly difficult to "understand" things that are completely untrue. Go ahead, give it a try. Try to "understand" that 1+1=3. Not so easy, is it?

I don't know how to type it on here, so it's a picture here:\n\nhttp://img516.imageshack.us/my.php?image=sillyequationsa5.jpg\n\nIt basically a complicated way of saying 1 = 1

Answer: 1\n\nThis is a trick question to check people's power of observation\n\nHere it is given 1 = 5. Therefore 5 = 1
