• curprev 19:3919:39, 3 August 2026 ~2026-42901-93 talk 52,181 bytes −139 Added the correct statement that the commutative property does not hold when we multiply a natural number n greater than or equal to 1 by 0. This follows directly from the fact that if we physically hold some object and we want to multiply it by 0, the object will not disappear; therefore, 0*n is undefined. Whereas, if we do not have any object and we want to multiply it by n, the result will always be 0. In other words, n*0 != 0*n undo Tags: Manual revert Reverted references removed
