Solve the following expression:
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 them,
Therefore we'll start by simplifying the expression inside the parentheses and perform the subtraction within them, then since division comes before subtraction, we'll first perform the division operation and then the subtraction operation
Therefore the correct answer is answer D.
Solve the following equation:
\( 30 - (10 + 7) = \)
Mathematics has a specific order of operations (PEMDAS) that must be followed! Working left to right gives wrong answers because some operations are more 'powerful' than others.
The colon (:) is another way to write division, just like ÷. So means the same as .
Use PEMDAS: Parentheses, Exponents, Multiplication/Division (left to right), Addition/Subtraction (left to right). A helpful phrase is 'Please Excuse My Dear Aunt Sally'!
If your check doesn't work, you likely made an order of operations error. Go back and carefully follow PEMDAS step by step, writing each step clearly.
Yes! Multiplication and division are always done before addition and subtraction, unless parentheses change the order. This is a fundamental rule in mathematics.
