Explain why it is important to use PEMDAS. Please give me at least three points or examples to support your answer. BRAINLIEST GIVEAWAY FOR CORRECT ANSWERS!!!

It's important to use PEMDAS to solve problems, to ensure that everyone solves a problem the same way. If I wanted to demonstrate how to do a problem, but used a different order of operations, I would get a different answer than everyone else. That wouldn't make me wrong, just different, which, in math, is unnecessary. Math has either a right or wrong, so if people got multiple answers for a problem that was supposed to only have 1, it would cause confusion. Additionally, when doing proofs, one needs to be able to reconstruct a scenario created. If PEMDAS didn't exist, then you wouldn't be able to always accurately reconstruct a scenario in math.
