Question

−3⋅(−5) -500⋅(−0,2)

Answer 1

−3⋅(−5)= 15

-500⋅(−0,2)= 100

Answer 2

To calculate the given expression, let's break it down step by step:

1. Start with the first term: -3 * (-5) Multiply -3 by -5: -3 * (-5) = 15

2. Move on to the second term: -500 * (-0.2) Multiply -500 by -0.2: -500 * (-0.2) = 100

Therefore, the final result is: 15 - 100 = -85
