Happy World Maths Day!

A Call for Unity
I'm not an expert, unfortunately, and I'm here a bit on shaky ground, but I believe there should be a clearer way of calculating. There are some controversial standards — PEMDAS, BEDMAS, BODMAS, BIDMAS — mnemonics of the order of operations. I can understand countries wanting to have freedom of expression, but maths should be a more exact science. I would say intuitively there can be only one type of this particular mnemonics and it should correlate perfectly with the observations in physics.
