According to the order of operations, we first solve the exercise within parentheses:
Now we subtract:
\( 100-(5+55)= \)
Mathematics has specific rules called order of operations (PEMDAS). Parentheses always come first, no matter where they appear in the expression!
Then you follow the rest of PEMDAS: Parentheses, Exponents, Multiplication and Division (left to right), Addition and Subtraction (left to right).
Yes! Order of operations ensures everyone gets the same correct answer. Without these rules, could have multiple different answers, which would be confusing!
Solve each set of parentheses first, then continue with the remaining operations. Work from the innermost parentheses outward if they're nested.
Think of parentheses as "do this first" containers. Whatever is inside must be completed before you can use that result in the rest of the problem!
