According to the rules of the order of arithmetic operations, we begin by enclosing the multiplication exercise inside parentheses:
We then solve the said exercise inside of the parentheses:
We obtain the following:
Lastly we solve the exercise from left to right:
-9
\( 8 + 3 \times 2 = \)
Mathematics has a special order called PEMDAS! If we solved left to right, everyone would get different answers for the same problem. The order of operations ensures we all get the same correct answer.
Parentheses, Exponents, Multiplication and Division (left to right), Addition and Subtraction (left to right). Remember: "Please Excuse My Dear Aunt Sally!"
Yes! Multiplication always comes before addition and subtraction in PEMDAS. In , you must calculate first, then work left to right with the remaining operations.
Try circling or underlining the operation you should do first! In this problem, circle the part. This visual reminder helps you tackle multiplication before moving to addition and subtraction.
Double-check your work step by step! Most mistakes happen when students work left to right instead of doing multiplication first. Remember:
