Показать описание
The order of operations helps us make sure we all get the same answer when doing a math problem (it's kind of a big deal). Watch an example that goes through the steps of PEMDAS. This will help you know in what order to solve your math problems.

Just when I think I know it, you continue to challenge my basic PEMDAS. AGAIN, thank you so much.

It's a good thing the solution wasn't much longer, otherwise you would have come round in a full circle the way your writing curves - but maybe that's an artefact of trying to write it and film it at the same time.
Often these "order of operations" problems are really nothing more than illustrations of ambiguously written expressions, and mnemonics like PEMDAS shouldn't really be necessary.
If more people used Reverse Polish Notation calculators there would be a lot less ambiguity.
