does 2+2 actually = 4? can you prove it?

[Anonymous No.14580786]

4 = 400x

100 = x

x + x = z

z = 4

2 + 2 = 4

2+2=8

[Anonymous No.14580797]

By definition, 2+2=4. Q.E.D.

[Anonymous No.14580817]

the successor of 2 is 3
and the successor of 3 is 4
that's how you get 4
the +2 just means apply the successor function twice

source?

2 + 2 = ( 1, 1, 1, 1 )

what is your proof that 3 is the successor of 2?

[Anonymous No.14580854]

let P(n) be the successor function such that P(n) = n + 1

P(1) = 1+1=2
P(P(1)) = 1 + P(1) = 1 + 1 + 1 = 2
P(P(P(1))) = 1 + P(P(1)) = 1 + 1 + P(1) = 1 + 1 + 1 + 1 = 4

o.t.o.h.

1 + 1 + 1 + 1 = (1 + 1) + (1 + 1) = P(1) + P(1) = 2 + 2

therefore 2 + 2 = 4

>but why le 1+1=2
because 2 is the successor to 1, we aren't adding anything here, think of it as "successor of 1", that's what the +1 does
>but le how
because we defined the natural numbers in this order: 1, 2, 3, 4, ...
so 1 is P(0), 2 is P(P(0)), 3 is P(P(P(0))) etc.
>but
It's counting.

thank you for getting in depth on this equation
