Simplify this expression paying attention to the order of operations. Whereby exponentiation precedes multiplication, division precedes addition and subtraction and that parentheses precede all of the above.
Therefore, let's first start by simplifying the expressions within the parentheses. After which we perform the multiplication between them:
Therefore, the correct answer is option B.
99
Solve the following equation:
\( 30 - (10 + 7) = \)
Because parentheses come first in the order of operations! You must complete the addition inside each set of parentheses before moving to multiplication between them.
You'll get the wrong answer! For example, if you multiply first, then add, you'd get 79 instead of the correct answer 99.
No! You can also use BODMAS (Brackets, Orders, Division/Multiplication, Addition/Subtraction) or GEMDAS (Grouping symbols first). They all mean the same thing!
Not exactly! You follow the order of operations first, then work left to right within operations of the same priority. Parentheses always come first, regardless of position.
Without parentheses, it would be . Then you'd multiply first: , which is completely different!
