  • "is no less than" means the same as "is greater than or equal to">/li>
  • The problem talks about how far apart numbers are from each other. This should tell us to use absolute value.
  • In general,
    abs%28x-y%29+%3E=+q
    is how one would say "the distance between x and y is greater than or equal to q" in mathematical terms.
  • Your problem can be reworded to: "Z's distance from 18 is greater than or equal to 8".
Combining all this together your problem becomes:
abs%28z-18%29+%3E=+8 [or abs%2818-z%29+%3E=+8]
