All in the source:
"This involves some fundamental, deep mathematics. The really hard thing is to show that 1+1=2. Once you have that, it's relatively easy to show that 2+2=4. What it means for 1+1 to equal 2 is that they're the SAME THING. That means
that if we do the same thing to both of them, we should get the same result. Let's take both sides of the equation and
add them to themselves. We can think about that as just adding the two
equations, like this:
1+1 = 2
+ 1+1 = 2
---------
1+1+1+1 = 2+2
Now think about the left side of the equation. What is "4?" Well, it's
just a name for the "fourth" (i.e., this many: * * * *) item in the
following list:
1
1+1
1+1+1
1+1+1+1
1+1+1+1+1
...
So "4" just means "start counting by ones until you reach the 'fourth'
item."
So we have this:
1+1 = 2
+ 1+1 = 2
---------
1+1+1+1 = 2+2
4 = 2+2

'2+2' is math, addition.
"What is 2+2" means "it's obvious", "it's simple".
Otherwise, I don't know what you're looking for, maybe 2+2=5.
