When is one plus one not always equal to two?

Answer 1

In words, "one plus one" is always equal to "two".

But in symbols, when writing these numbers in binary representation,

1 + 1 = 1 0 .

When you're reading binary numbers and you see "1 0" on the paper,

you say either "one zero" or "two". You do not say "ten".

Answer 2

It is called synergy. If two people work separately then 1+1=2. But if two people work together, then they do more than two people working separately could do. Therefore it creates three, rather than two. Then, 1+1=3.

Answer 3

In science (e.x. if u add 1 cup of water to 1 cup of alcohol, you won't get 2 cups of liquid).

Answer 4

If you count to 1 then count up again then that proves that 1+1 actually = 2 not 1

Answer 5

In nature, 1+1 can equal three...

Answer 6

No. It equals 2.

Answer 7

When it's one half + one half?
