What is 1+1 ?

Question

Best Answer will be the most complete one that answers almost all possibilities- from absolute to relative, scientific to artistic, linear to lateral, microscopic to universal etc. :)

Answer 1

1+1 is equal to 2. if you think it is more then i will give you 1 dollar and 1 dollar and then you give me more or if you think it is less then you give me 1 dollar and 1 dollar and I will give you less!!!!

Answer 2

1+1=2

Answer 3

1

Answer 4

2

Answer 5

2

Answer 6

OK, by our conventions today, it is defined as 2.
If you drop that convention it could be anything, or
you could use roman numerals and get II. Or - in some
foreign language it could be the symbol for "carrier bag"
or "window".
I like especially the answer "zero plus a carry".
In fact you have some very good answers already for
that silly question :). I'll also try and write something
sensible.

Numbers were introduced for counting - thus assuming
that many things may be the same, you can count them -
coins for example. This is only a simplification in our heads.
In reality no two things are ever perfectly equal, just similar.
So by adding you make some kind of simplification error.

Still it makes sense to have numbers. To count similar items
for a start and then further on to apply maths to the
description of happenings in nature. Latter allows our technology.
Finally, it is also good for mathematicians on an even higher
level with their complex vector spaces for example where applications still have yet to be found.

Again to your question. It does not matter how you define 2. It
could be "thud". Thud would take more time to write and you
would be slower doing maths. Specially if you would have to chisel the numbers into stone! Then II would be even better than 2.

Answer 7

Mathematics:
1 + 1 = 2
1.0 + 1.0 = 2.0
1/1 + 1/1 = 1/1 = 2/2 = 2

Chemistry:
Molar mass of hydrogen = 1
1 + 1 = 2, which is the molecular mass of a H2 molecule.
1 helium atom (4g) is the molar mass of (1+1)*2 hydrogen atoms.

Answer 8

in base 2 it's 10. in base 10 it's 2.

Answer 9

You see when man first began to think mathematically he saw something (say a stone). So, he named the quantity of that object 1. Then he saw two stones and named this quantity as 2.
He understood that if he brings one stone together with another stone he will get two stones. So, he created a function which puts together the quantities on which the function is being applied on (addition). So, when the function of addition is applied on two units we get two. It is all because we defined two unit quantities as two.
