(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I need to determine if a*b=ab+1 is commutative and associative.

* is any arbitrary operation

2. Relevant equations

3. The attempt at a solution

a*b=ab+1 is commutative, but not associative.

I'm getting stuck in showing why.

b*a=ba+1

a*(b*c)=a(b+1)

?????
