    (-1) (15+15+15+15)

    (-15) + (-15) + (-15) + (-15)

    Step-by-step explanation:

    1. The multiplication shown in the problem above is:

    4 (-15)

    The product is - 60

    4 (-15) = -60

    2. The multiplication above could indicate that:

    - The number - 15 is added 4 times.

    - The number 15 is added 4 times and then is multiplied by - 1.

    - The number - 4 is added 15 times.

    - The number 4 is added 15 times and then is multiplied by - 1.

    Keeping these on mind, you can conclude that the correct options are the third option and the last option:

    (-1) (15+15+15+15) = (-1) (60) = -60

    (-15) + (-15) + (-15) + (-15) = -15-15-15-15=-60
