What's 1 + 1?

1 male + 1 female could mean several

1+1=11
1+1=41

2

1 + 1
= 10 (binary form)

it is equals to 2

but if is joke then it will be 11

depends on the characterictic of the field:

1+1=2, if Char F=0,
1+1=0, if Char F=2...

It depends on the definition of 1 and +.

Fuller's proof that 1 + 1 = 4 in his book synergetics is interesting.

Yesterday, a friend told me of a T-shirt he gave someone (really into computer programming) with the following message:

There are 10 kinds of people: those who understand binary and those who don't.

3

(because 1=2)

(oh, by the way, 1+1=10 in binary, and "1"+"1"="11" (string concatenation))

o in binary, and 2 in any base other than 2.

1+1=1
