السؤال 30

What is the value of -|-5|?

  1. 5
  2. -5الإجابة الصحيحة
  3. 0
  4. Undefined, because a minus sign cannot stand outside absolute value bars.

الشرح

The bars are worked out first and hand back the distance five, and the minus sign written outside them then reverses that result. Reading the two minus signs as a cancelling pair gives 5, yet only one of them belongs to a value; the outer one acts on the finished distance.
