When solving mathematical expressions, multiplication must be performed before subtraction according to the order of operations (PEMDAS), and when multiple operations of the same priority exist, they should be evaluated from left to right. For example, in the expression 6 - 6 * 6 - 6, the correct solution is -36, not 0, because the multiplication (6 * 6 = 36) must be calculated first, followed by the subtractions from left to right (6 - 36 = -30, then -30 - 6 = -36).
