Absorption rule in Boolean algebra

Question

I am confused regarding the absorption rule which states: A OR (A AND B) = A.

I do not completely understand how the expression simplifies to A and while i have seen proofs for this question, i still feel that i don't completely grasp it.

I will outline my working out below:

if expression = A OR (A AND B) then, according to the commutative rule we can rewrite this as (A OR A) AND B. (A OR A) simplifies to A. This means we should be left with A AND B. However, the expression simplifies to A which i don't understand. Why is this the case?
