“In mathematics, the distributive property of binary operations is a generalization of the distributive law, which asserts that the equality x*(y+z) = x*y + x*z is always true in elementary algebra.”
This is the first sentence of the article, which clearly states that the distributive property is a generalization of the distributive law, which is then stated.
Make sure you can comprehend that before reading on.
To make your misunderstanding clear: You seem to be under the impression that the distributive law and distributive property are completely different statements, where the only difference in reality is that the distributive property is a property that some fields (or other structures with a pair of operations) may have, and the distributive law is the statement that common algebraic structures like the integers and the reals adhere to the distributive property.
I don’t know which school you went to or teach at, but this certainly is not 7th year material.
