Addition and subtraction have equal priority in the order of operations! When operations have the same priority, you must work left to right. This prevents confusion in more complex problems.
Remember PEMDAS: Parentheses, Exponents, Multiplication/Division (left to right), Addition/Subtraction (left to right). Since this problem only has addition and subtraction, go left to right!
Actually, for this specific problem , you get the same answer either way because of how numbers work. But always follow left-to-right to build good habits for harder problems!
Try working backwards: Start with your answer 12, add 3 to get 15, then subtract 5 to get 10. If you get the first number from the problem, you're correct!
The same rule applies! Work left to right, one step at a time. You might want to write down your intermediate steps to avoid mental math errors with larger numbers.
