Things to Do with Real Numbers Examples
Since -200 is to the left of 5 on the number line, we say that -200 is less than 5. This is abbreviated in symbols by:
Remember that the absolute value of a number is the number of steps it takes to reach that number from zero. (You can only take one step at a time. We're very impressed that you can jump all the way from 3 to 7 in a single bound, but you're going to have to pull it back a skosh.) |-200| = 200 so, the absolute value of (-200) is greater than 5. Show this as an inequality.
Show n in an inequality if n is any positive number...
