what is 1 plus 1?

Question

idk i just wanna see what people will say.

Answer 1

That is 2.

Answer 2

Andrei already noted that 1 (a single) plus 1 (positive value of one) = 1


we could keep it mathematical but.... in mathematics there are inifinite abstractions of every value:
1 + 1 = 1! + 1! = 3 -1 = 2*1 = 2! = 817449064/408724532....

And mathematical languages such as
binary 1+1 = 10
Logarithms 1+1 = 1 log(100)

and..... well, keep it up for long enough and there may be nothing 1 plus 1 can't be in at least one form or another. That's probably what you were expecting, right?

Normally it's pretty much two. But if you WANT to argue about 1+1=2, there are any number of things that are assumed in math that you could choose to challenge if you wish. For example:

TWO HAS A CONCRETE DEFINITION. What really IS two? Some would argue that it's not as certain as many make it seem. Two people are made up of hundreds of organs and zillions of atoms. Is it appropriate to call them 'two', considering that? What if one of the two is pregnant - are they two or three?

MATH IS ONLY APPROXIMATION. A two could be said to be proceeded and followed by an infinite number of zeroes. But it is possible to really affect things that are infinite? There are mathematical ways of determining such things, and they seem to work, but what if this function is only an illusion. If 1.9 repeating is the same as two, does that not hint that two is not really concrete?

SUMMATION RETAINS DISTINCTNESS. If you take two small glasses of water and pour them into one large glass, how many glasses do you have? One. 1+1=1. If you take two fighting fish in put them in the same tank, how many will you have? One (after a moment or two). If you take two willing adults of different sex and lock them in a room together with lots of food and check back in a year or two, you may find three people in that room. 1+1=3. Depending on how things interact, you may easily have much more or less of what math might predict when you start putting things together!

ALL THINGS CAN BE ADDED. One apple plus one orange equals one apple and one orange. 1+1 = 1+1. You will never get two apples or two oranges this way. Oil plus water equals oil and water. Some things do not add, mix, or go together, no matter how much you try!

THERE IS MORE THAN ONE THING IN THE UNIVERSE. There are those who would argue that all things are really just manifestations of one thing, and that plurality in the universe does not in fact exist. If this is so, then even 'two' is impossible, except as a manifestation of the one. If there is only Tao, then 1+1=1, not 2.

THE EQUATION HAS MEANING. Even if we all agree on the meanings of the components and the function of math, we may dispute that math has any actual application to the real world. For example, there is no 'two'. There are two OF things, but the universe does not contain an essential 'two'. So where is the two? In our minds. This arguably, makes it about as real as dragons, unicorns, and other things which can only be found entirely in our minds.

I'm sure if you think about it, you can probably think of many more. It is an interesting thought exercise to see all the assumptions that are made on a regular basis. Whether it is useful to BEHAVE as if all these assumptions were untrue is, however, a completely different discussion.

Answer 6

If we are only to consider the calculational definition, then 1+1=1+1. "2" would just be shorthand for 1+1. "2" would just be a symbol for an accidental collection of two units. However, apart from purely calculational considerations, two has a unity which is beyond merely "1+1." In other words, if we consider two according to what it is, it is a certain number of units (which is distinguished by containing one more than unity). If we consider two merely according to what we can do with it--i.e. calculationally--it is no more than 1+1.

Answer 7

Depends on your notation and modulus. For those that don't dig that statement: 1+1 in binary =10, there is no 2 just 1 and 0

Answer 8

Do you mean (1 + 1) or (1 + 1?) ? The Minkowski question mark function can be important.

To be different though I will use hexidecimal and say 1 + 1 = 2. Oh, wait, it's the same.

Answer 9

the answer is 2...but in the binary code that computer is using, 1+1=10.......
computer only can process the number 0 n 1....

Answer 10

1 more than you had before!!!
