Question 885213
You can use integers in these (and many more) ways:
* Balancing your checkbook (negative integers if overdrawn; positive if a balance)
* Eating and exercise - Counting calories to make sure you've eaten enough to compensate for your exercise.  How many calories burned on your run (subtract)?  How many in that nice, delicious, juicy steak? (add)
* Stock Market - Is the Dow Jones climbing or falling?  What happened to Hobby Lobby's stock after the recent Supreme Court decision in their favor?  If you check a stock site, usually stocks that are rising in price will be in green, and those that are falling will be in red.
* Weather.  What's the weather like outside?  Is it hot (90F) or cold (-3F)?  
* Elevation.  Is a location above or below sea level?  How far above or below?
* Speed Limit.  Are you going over (positive) or under (negative) the posted speed limit?  
* Do you like to play golf?  Over par (positive) is actually a poor score; under par (negative) is what you're after.
* History timeline - Did an event happen AD (Anno Domini) or BC (before Christ)?
