Order of Operations: First, we need to follow the order of operations, which is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). This rule is often abbreviated as PEMDAS. Since there are no parentheses or exponents to deal with in this problem, we start with division.Calculate 90÷10.90÷10=9
Division Calculation: Now, add the result of the division to 3. 3+9=12
