Question 65

Select all statements that are true about the product (-13) * 0.

  1. The product is -13, because multiplying by zero leaves the other factor unchanged.
  2. The product is 0.Bonne réponse
  3. The product is 0 whatever the sign of the other factor.Bonne réponse
  4. Zero times an integer is zero however large that integer is.Bonne réponse

Explication

Taking a quantity zero times collects nothing at all, so the result rests exactly at zero however large the other factor is and whichever side of zero it lies on. Treating the zero as though it left its partner untouched confuses it with one, which is the factor that really does preserve whatever it multiplies.
