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.
