Question

what is 2+2 the answer is not 4 because 2×2 are 4​

Answer 1

Answer:

Explanation:

It depends on what axioms you allow, but if you allow me Peano Arithmetic, then we can proceed as follows,

2=S(S(0))  by definition.

4=S(S(S(S(0))))  by definition.

Addition is defined by  x+0=x  for all natural numbers  x , and  x+S(y)=S(x+y)  for all natural numbers  x,y .

Therefore

2+2=S(S(0))+S(S(0))  

=S(S(S(0))+S(0))  

=S(S(S(S(0))+0))  

=S(S(S(S(0))))  

=4

Answer 2

Explanation:

bhai question to right hy lykin hmm jo addition krty hy na woo ek hi digital ko bar bar repeat krty hy aur multiple ka ky hota hy na ki us my hmm ek digital ko lyty hy aur duary digital ko kitni bar multiple times karna hy usse multiple krty hy
