Let's simplify this expression while following the order of operations which states that exponents come before multiplication and division, which come before addition and subtraction, and that parentheses come before all of these,
Therefore, we'll start by simplifying the expression in parentheses, and since division comes before addition, we'll first perform the division operation in this expression and then the addition operation:
We'll continue to simplify the expression we got in the last step, remembering that multiplication comes before addition and therefore we'll first perform the multiplication in the expression and then the addition operation:
Therefore, the correct answer is answer C.
Solve the following problem:
\( 187\times(8-5)= \)
Order of operations (PEMDAS) ensures everyone gets the same answer! Without these rules, could equal 20 or 16 - math would be confusing and inconsistent.
The colon (:) is another way to write division, just like ÷. So means 6 divided by 3, which equals 2.
No! Even inside parentheses, you still follow order of operations. So in , do the division first: , then addition: .
Use PEMDAS: Parentheses, Exponents, Multiplication/Division (left to right), Addition/Subtraction (left to right). Remember "Please Excuse My Dear Aunt Sally"!
Double-check each step! The most common mistake is ignoring parentheses or doing addition before multiplication. Write out each step clearly and follow PEMDAS exactly.
