Question

Guys help
I don’t know what 2+2 is

Answer 1

Okay I'm gonna help you out. Let's make things easier.

Let A = {a,b}

and B = {x,y}

Assuming that a ≠ b ≠ x ≠ y

If I see their cardinality, (note that there only 2 elements in either of the sets which is finite) then,

|A| = 2......(1)

|B| = 2........(2)

From 1. and 2,

|A| = |B|

By the definition of addition,

|A| + |B| = 2 + 2 = 4

Hope you understood the underlying concept, i.e., if you take 2 2s and put them together they'll always result in 4.

Answer 2

It's 4

Explanation:

2+2 =

1+1+1+1 =

0.5 + 0.5 + 0.5 + 0.5 + 0.5+ 0.5 + 0.5 + 0.5

and so on.

It's a really complicated proof, so you're gonna have to take my word for it. Sorry about that.
