Answer:
Yes
Explanation:
PEMDAS explains the order that operations are done.
PEMDAS
PEMDAS stands for Parentheses, Exponents, Multiplication and Division, Addition and Subtraction. This is the order of operations. Always start with operations inside parentheses, then exponents, then multiplication and division, and the last operations are addition and subtraction. In the problem above, parentheses come first, so means start with 18 x 8 and then do subtraction afterward.
Without Parentheses
Take the new expression, 252 - 18 x 8. Following the order of operations, multiplication goes first. This means multiply 18 x 8 first and then subtract. This order of operations is the same with or without parentheses. Since multiplication comes before subtraction, parentheses are not needed.
