Question 17

Which is the greater value, -7 or -2?

  1. -7
  2. -2Bonne réponse
  3. They are equal, because both lie left of zero.
  4. Neither, because negative values cannot be ranked.

Explication

On the negative side the line rises towards zero, so the mark two steps below zero stands to the right of the mark seven steps below it. Choosing -7 weighs 7 against 2 and ranks the magnitudes, which reverses the true order once both values carry a minus sign.
