Solve conceptually challenging absolute value problems. In order to succeed at these problems, you'll need to remember that the absolute value of the difference of two numbers is the distance between those numbers.


Match each expression with its appropriate interpretation.
  • 7, minus, 9
  • open vertical bar, 7, minus, 9, close vertical bar
  • 7, plus, left parenthesis, minus, 7, right parenthesis
  • Sums to zero
  • The distance between 7 and 9 on the number line
  • The number 9 to the left of 7 on the horizontal number line
