Question

What is 2+2 I am very confused

Answer 1

The answer is 4, it's just 2+2=4, for example I have two apples, you have two apples also. How many apples do we have in total? (2+2=4)

Answer 2

In base-3 numbers,  2 + 2 = 11 .

In base-4 numbers,  2 + 2 = 10 .

In any base larger than 4, including
our familiar every-day decimal system,  2 + 2 = 4 .

I can't imagine why you would really need to post this question
and look for answers on the internet.  Perhaps, as you have said,
you are just very confused.
