If \(x\ge y\)and \(d>0\)(positive number) , then \(dx\ge dy\) and \(\frac{x}{d}\ge \frac{y}{d}\) (sign is not reversed) | |
If \(x\le y\) and \(d>0\)(positive number) , then \(dx\le dy\) and \(\frac{x}{d}\le \frac{y}{d}\) (sign is not reversed) | |
If \(x\ge y\) and \(d<0\), then \(dx\le dy\) and \(x/d\le y/d\). | |
If \(x\le y\) and \(d<0\), then \(dx\ge dy\) and \(x/d\ge y/d\). |
