Evaluate the following expression 5(1 3)-3(2 -1)
BARSIC [14]

Answer:

Step-by-step explanation:

This problem tests your understanding of order of operations rules.

Here you must do any work inside parentheses first, followed by multiplication, followed by subtraction:

5(13) - 3(2 -1) would be 65 -3(1), or 62.

If you actually meant 5(1 - 3) - 3(2 - 1), then you'd have

5(-2) - 3(1) = -10 - 3 = -13

Please compare the problem you've shared with the original problem, to ensure that these match.
