Pregunta 91

Consider the expression -24 / (-6) * 2. Select all statements that are true about the way it is evaluated.

  1. Its value is 8.Respuesta correcta
  2. The division and the multiplication rank equally, so they are worked from left to right, which puts the division first here.Respuesta correcta
  3. Its value is 2, because the multiplication is carried out before the division.
  4. Its value is -8, because a negative shared into negative parts stays negative.

Explicación

Operations of equal rank are worked through from left to right, so twenty-four below zero is shared into parts of six below zero to give four, and doubling that gives eight. Multiplying the six by the two first regroups the expression into a different one, and the two negative signs cancel rather than survive into the result.
