    What is the multiplicative identity? It's a number.

    No need to go that far @projects :) The question asks for the commutative property not the associative property

    3 is the only number that will make that equation a true statement That is, both sides will have the same value.

    New students should learn that the equals sign is used to show That the two expressions on either side have the same value. 4 + 2 = 6 is true because 6 = 6 is a true statement.
