Complete the exercise:
According to the rules of the order of arithmetic operations, we begin by placing the multiplication and division exercises inside of parentheses:
We then solve the exercise within the parentheses:
We obtain the following :
Finally we solve the exercise from left to right:
19
\( 8 + 3 \times 2 = \)
Mathematical operations have a specific order that must be followed! If we solved left to right, we'd get 43 instead of the correct answer 19.
Parentheses, Exponents, Multiplication and Division (left to right), Addition and Subtraction (left to right). Remember: Please Excuse My Dear Aunt Sally!
Writing can help you visualize the order, but it's not required. The multiplication has priority whether you write parentheses or not!
Solve all multiplications and divisions first, working from left to right. Then do all additions and subtractions, also from left to right.
After getting your final answer, retrace each step: First , then left to right gives 19. Double-checking prevents silly mistakes!
