But 5 + 2 x 6 can be confusing without the parenthesis. Without the parenthesis the answer is 17 because of the order of operations rule. For the answer to be 42 you have to have parenthesis around 5 + 2. You can't just go from left to right, you have to multiply and divide before you add or subtract.
