1 + 1 will always equal 2 unless the definition of 1 means something else. If 1 + 1 = 3, 1 would actually be 1.5 not 1.

1+1 will always equal 2 unless you change the value of what 1 is. 1+1=3 would actually be 1.5+1.5 = 3.
@Jzonda, talking specifically about weight yes 1 liter of water plus 1 liter of vinegar would equal 2 liters. Maybe you meant to say a half cup of vinegar does not weight the same as a half cup of water?

Yes unless the government tells you otherwise. (sarcasim) if gov desided to say it = 3 tomarrow, everyone would have to call it 3 so they didnt mess up their tax forms and so they'll get a good grade.

Heh... 1984.

Unrelated "related topics" much?

In estimation if you truncate the values, 1+1 will still equal 2, but it may not be the most accurate answer.

If there is a mathematical fallacy in the proof or a contradiction. Are you including the possibility of zero in the factor? And is it Euclidian Geometry, calculus, or elementary algebra?

I recomend a book called "GĂ¶del, Escher, Bach: An Eternal Golden Braid".
If you have two rain drops on your window and you say 1 rain drop plus 1 raindrop = 2 raindrops but you look again and one of the raindrops split now you have 3 raindrops. So 1 + 1 doen't always = 2

The question never said does the whole number 1 plus the whole number 1 = the whole number 2.

The question never said does the whole number 1 plus the whole number 1 = the whole number 2.

What else would we assume 1 and 2 equal? Unless otherwise specified, 1 does necessarily equal the whole number 1.

In programming "1" + "1" will print out 11 as the computer treats the 1 as though it were a letter. Remember algebra, where a + b = ab?

If I was a political activist I'd say 1+1 can equal whatever it wants and we shouldn't discriminate. But knowing that 1+1 is 2 and cannot be anything else unless 1 is not 1 which means it is already a different answer, I'd say it cannot be whatever it wants.

In base 2, 1+1=10

I never get these questions. Can someone please explain the other side to me?

Assuming actual, whole numbers, rather than something stupid like 1.4 +1.8, which leads to a different logical answer, then yes.

I feel like this is a trick question...

Its kind of like a tautology; we define values such as "1" and "2." The answer of the equation 1 + 1 is, by definition, 2.

Because this is an absolute. Core curriculum with an emphasis on math would love for us to believe this but the very notion is dumb.

1+1 is obviously 2 by standard math rules.

For extremely large values of 1, 1+1 can =3

It can depend on what the numbers represent. For instance, one liter of water added to one liter of vinegar does not equal two liters of liquid.

mathematically speaking, yes.

1+1 can = 3

No, because what if the + is representing and, then it is eleven.
