Sales â Cost of Sales = Gross Profit â Operating Expenses = Operating Income. Using the operating income margin as an indicator--computed by simply dividing operating income by total sales--will allow you to measure managementâs efficiency in running the business.

Snakes 'hiss' - It sounds just like the sound humans make when they say the letter 'S' out loud. One of my favourite past-times is driving and exploring with my husband (and my dog). In WikiAnswers, I am constantly On the wallaby.
The Madagascar hissing cockroach is one member of a group of roaches that can all hiss; this exact mode of sound production is atypical, as most insects that make sound do so by rubbing together various body parts ( stridulation ), such as legs. Madagascar hissing cockroach has been used as the driver of a mobile robot. They were used in the reality television series Fear Factor. The species also made an appearance in the movie Men In Black in 1997.
