$2\mathrm{.}2\mathrm{.}3.$ The degree of complexity of AinForm$(L^p)$ is defined by recursion:

deg$(A)=0$ for atom $A.$

deg$((notA))=$deg$(A)+1.$

deg$((A**B))=$max$(deg(A),$deg$(B))+1$

$[1]$ Show that deg$(A)$ the number of occurrences of connectives in

A$.$

$[2]$ Give examples of A such that $$ or $=$ holds in $[1].$
