Look, I gave you a link to the BBC explaining the order of operations. They absolutely exist and they're a standard of Math period. Just like I showed Divvy in the above post they're important or you'd come up with different answers to the same equation which doesn't work for Math.
Anyways I'm done, if you guys still don't believe me after it's been explained over and over again then that's your choice.
