Hardest question any one will answer cant be found by google.?

Question

What is 1 + 1 equal

Prove it,
What says that that's the right answer?
Why can it equal 11?

Answer 1

using that crappy formula any math major gets put through while taking fundamentals of algebra or any other proof/theory class for that matter 1+1 could equal 50 million but the only reason the dang thing works is because halfway through the problem the question zeroes out.

Most students are to dumb to catch this and are in awe of how pointless this little trick is other then toying with children. That and showing anything can be possible if you play with the numbers enough.

Edward W is correct in his statement.

here have fun with this.
-1²=1²
(1-2)² = (2-1)²
Taking square root on both the sides,
1-2=2-1
2=4
Dividing both the sides by 2,
1=2.
But we know 1+1=2,
Therefore,
1=1+1
or
1+1=1

Answer 2

The world consists of 10 types of people. Those that understand binary and those that do not.
That joke points out that everything comes down to the definition of the terms we use. President Clinton once famously said something like "It all comes down to what the definition of the word is is.
If the definition of 1 is the number of items counted when you have only counted the first item in a list and if "+" means to determine how many items would be counted if one counted to the amount on the left of the plus sign followed by counting additional items consistent with the number on the right of the plus sign then
1 + 1 means the same thing as 2

There are much more complicated answers that come out of real numbers rather than counting numbers and even more complicated answers that come out of using complex numbers.
This is a question that could be answered at many different levels. It is possible for doctoral candidates to continue to find new ways to think about your question.

Answer 3

Maybe it can't be found on google, but it can on yahoo answers, I have answered it before. ( http://answers.yahoo.com/question/index;_ylt=AuDfFbV48MdK6SCzq_qtKfzsy6IX?qid=20061218071248AAVGkrU&show=7#profile-info-2e55d9aca715bf6d1996b5086fa0c234aa )

You haven't studied math, have you?

You need to understand what "proof" means, technically. It means to start with axioms that you know and logically deduce something from them.

You also need to define what the symbols mean - if you are working in base 2 then 1 + 1 = 10, otherwise 1 + 1 = 2.

See the reference for a more complete explanation, basicly the natural numbers are defined by defining the number 0 such that 0 + a = a for all a, and defining a successor function s(a) == a + 1. Then 1 is defined as s(0), 2 as s(s(0)), 3 as s(s(s(0)))...

So 1 + 1 = s(0) + s(0) = s(s(0)) = 2. QED.

Answer 4

We do not prove that 1 + 1 = 2, we define the operation of addition on the (algebraic) ring of integers so that when 1 is the integer we all know, then 1 + 1 = 2. When we define addition this way, it turns out to be very useful.

You may define some operation "+" on the integers, so that 1 "+" 1 = 11, and if that turns out to be useful to you, then that is a perfectly (mathematically) legitimate thing to do.

Answer 5

You get into this kind of stuff with number theory. We just have to take this as a granted that 1+1=2. The mathematical term for this is an "axiom"

Answer 6

One approach is to take it to a real world situation.

Take one rock, label it 1.
Take another rock, label it 1 also.

Place the two rocks next to each other, then count the number of rocks, is it 2 or 11? I pick 2.

Answer 7

that is an rather good question.! i imagine it truly is relaxing to respond to yahoo solutions and some ppl the picture of asking questions yet some questions won't be able to be discovered on google yet I hate searching and would fairly ask questions about yahoo solutions...

Answer 8

I'd suggest consulting the Principia Mathematica by Russell and Whitehead.

Answer 9

1+1=2

What are you talking about?

Answer 10

one of something plus another one of that thing then it will be two of those things
