However, you have to be very careful about the direction of the inequality! The division property of equality states that when we divide both sides of an equation by the same non-zero number, the two sides remain equal. In other words, not every relation of real numbers fulfills this property. The proof of the Archimedean property that I am familiar with relies on the connectedness of real numbers, but, if I'm not mistaken, it is possible to prove that the real numbers (taken to be Dedekind cuts) are connected without ever talking of the additive identities of cuts. Multiplication Property of Equality states that when we multiply the same quantity to both sides of an equation, the equation remains true. See answer |y| is always >=0 Writting -|-x|=7 is a non-sense! 3. Definition Multiplicative property of equality.
