like how does it make sense? why is it correct compared to just solving equations left to right? what are some scenarios that prove PEMDAS to be the absolute truth and necessity? @_@

PEMDAS is just a convention we agreed to write with – just like how we all agree to read English left to right and not top-to-bottom. As for why it is convenient – I think PEMDAS makes writing polynomials the neatest.
