Complete the exercise:
According to the rules of the order of arithmetic operations, we must first place the multiplication and division exercises within parentheses:
We then solve the exercise inside of the parentheses:
We obtain the following exercise:
Finally we solve the exercise from left to right:
9
\( 8 + 3 \times 2 = \)
Order of operations (PEMDAS) is a mathematical rule that everyone follows! Without it, the same expression could have multiple answers, which would make math confusing and unreliable.
The colon (:) means division, just like the ÷ symbol. So is the same as .
You don't need to write parentheses, but adding them like can help you visualize which operations to do first!
That's normal! In this problem, , but then we add 10 to get . Keep going until you finish all operations.
Use the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (left to right), Addition and Subtraction (left to right). Some students remember it as "Please Excuse My Dear Aunt Sally"!
