Does 1+1 always equal 2?

ummmmmmmm, no it can also equal u and me. love you.

In math yes. In philosophy the the numbers are not real. in relationships it might equal 3 if you arn't careful

Actually, if talking about statements in pre-calc or calculus, its doesnt have to. Logic is a great section in calc, and its easy, therefore 1 + 1 can equal 3, and that statement would be true.

It depends upon how you define 1 and how you define +, and how you define " 1 + 1 ".

If all those symbols have their usual, ordinary, mathematical definitions, then yes, 1 + 1 always is equal to 2.

But lots of tricky, supposedly clever (!), as well as a lot of extraordinarily dumb folks, will try to put any number of different interpretations upon it. Let's hope they can find their way back to the asylum.

well in the rule of philosophy, evalation, and physics 1+1 can equal ANYTHING above 2

take your parents for example you have a mom and dad 1+1 and they have you that is 3 so in this case

1+1=3 but it could be more if you have twins or something

You can define the symbols 1 and + to mean almost anything you want. If 1 is an element of the integers modulo 2, and + means addition modulo 2, then 1+1 = 0. If you are operating in binary, 1+1 = 10. If 1 is just a symbol in some alphabet and + is the concantenation operator (which it never is, but why not define it that way) then 1+1 = 11. However, if you are using the standard integer 1 and the standard addition operation +, then 1+1=2, always. Mathematically, philosophically, scientifically, it doesn't matter, it's always equal to 2.

yes. but some people say it equals window cuz if u put 1+1= all on top of eachother you get a window.

yeah 1+1 is always equal 2 but not 1-1 or 1*1 or 1/1.

1 + 1
= 2 (in decimal system)

1 + 1
= 10 (in binary system)

If you are taling about .11 (eleven hundredths) or 1 hundredth and 1 tenth (100+10) No it could be different...

1 + 1 = 2
