Answer 3

To calculate the expression -59.3 + (-78.7) + 59.3 + (-78.7), you can combine the positive and negative numbers separately and then sum them up.

First, let's add the positive numbers: 59.3 + 59.3 = 118.6.

Next, let's add the negative numbers: -78.7 + (-78.7) = -157.4.

Finally, let's sum the results of the positive and negative additions: 118.6 + (-157.4) = -38.8.

Therefore, -59.3 + (-78.7) + 59.3 + (-78.7) equals -38.8.
