In the mathematical order of operations, we first perform any calculations inside parentheses, then any exponents, then any multiplication or division (working from left to right), and finally any addition or subtraction (working from left to right). In this expression, there are no parentheses or exponents, so we must perform the multiplication and division before the addition and subtraction. Therefore, we first evaluate 4 * 3, which equals 12. Next, we evaluate 15 / 3, which equals 5. Then, we subtract 6 from 12 to get 6, and finally we add 5 to get 11. Since subtraction is performed last in this expression, the answer is B) -.
