People keep debating over this stuff. I have a simpler solution. Math is not real.
The only real answer lmao. People really out here thinking the funny symbols on the paper follow absolute laws. Crazy.

They do. Maths is universal, just like the laws of Physics (which are often written using Maths BTW).
My momβs a mathematician, she got annoyed when I said that the order of operations is just arbitrary rules made up by people a couple thousand years ago
Itβs organized so that more powerful operations get precedence, which seems natural.
Set aside intentionally confusing expressions. The basic idea of the Order of Operations holds water even without ever formally learning the rules.
If an addition result comes first and gets exponentiated, the changes from the addition are exaggerated. It makes addition more powerful than it should be. The big stuff should happen first, then the more granular operations. Of course, there are specific cases where we need to reorder, or add clarity, which is why human decisions about groupings are at the top.

The βbig stuffβ is stuff that is defined in terms of something else. i.e. exponents are shorthand for repeated multiplicationβ¦ and multiplication is shorthand for repeated addition, hence they have to be done in that order or you get wrong answers.

Iβm not surprised. Hereβs the proof of the order of operations rules. Also, the equals sign wasnβt invented until the 16th century, so only 500 years old at most (the earliest references to order of operations are over 400 years ago).
That proof for the order of operations sure seems to rely a lot on our current order of operationsβ¦
Iβm with you. Has anyone ever actually seen a math? Can you buy a math at the math store? Are there bespoke math craftspeople?
No.
I rest my case.
βMathβ is a mass noun. You canβt have βa mathβ. Itβs like blood or love. You can have more blood or less blood. There might be units in which blood is measured that you can have a certain number of (βa gallon of bloodβ), but you canβt have, unqualified, a blood or two bloods (well, not in that sense of the word, anyway).
