Solve the following problem using the order of operations:
According to the order of operations, we'll first solve the exercises in parentheses:
We should obtain the following exercise:
We'll place the multiplication exercise in parentheses to avoid confusion in the rest of the solution:
According to the order of operations, we'll solve the multiplication exercise and then add:
\( 100+5-100+5 \)
Mathematics has a specific order called PEMDAS to avoid confusion! Without it, the same expression could have different answers. Parentheses always come first, no matter where they appear.
Yes! Writing each step helps you avoid mistakes and makes it easier to check your work. Show the parentheses calculations first: and .
You'll get the wrong answer! For example, doing first gives you , which is completely different from the correct answer of 94.
Absolutely! After solving, try working backwards from your answer. Does and ? This matches our parentheses results!
Even though addition appears last in the expression, multiplication always comes before addition in PEMDAS. So must be calculated before adding 4.
