which means, start with Parentheses (or BRACKETS);  
 THEN do exponents;
Then "multiplication division" (from left to right as they appear);
Then "addition subtraction" (from left to right, as they appear).

The three (3) answer choices given are:
_____________________________
   a) parentheses ;
   b) exponents;
   c) multiplication division.
____________________________
We know from our mnemonic that BOTH parentheses AND exponents (i.e. choices "A" and "B" come before "Multiplication and Division" (answer choice "C"); so we can rule out "answer choice C".  We are left with answer choices: a) parentheses; and:  b) exponents.  We know from our mnemonic that parentheses come before exponents, so, we rule out "answer choice B", and we know that "answer choice: {A}: parentheses" — is the correct answer.

The operation that should be performed first for calculations involving more than one arithmetic operation is A) Parentheses.

  • In the mathematical formula, BODMAS, we see the sequence that should be followed when we have mathematical operations that require several operations.

  • The operations in the bracket or parentheses should be attended to first before performing any operations outside the bracket.

  • Therefore, option A is the right answer.
