We got more people who don't know PEMDAS (or BODMAS). 🤣

@Rolexeo In order to standardize notation.

@Rolexeo That's a good question, I have yet to know. Maybe it makes it easy for equations to get easier? I'm not so sure.

@xSiFiGamer2016x is simply the way we've decided to write it. By having specific rules about how we write it we can get consistent results and understanding between people.

@ViciDraco so it's basically just agreed upon?

@Rolexeo Yes. You have to remember that the math we write is a representative description of what is happening. The formulas describe the physical math that is happening. Just like we use our words to describe objects, events, and concepts.

I had ten dollars. I doubled it and then Jimmy took two. I have eighteen dollars.

10 X 2 - 2 = 18

I had ten dollars. Jimmy took two of my dollars and then I doubled the rest. I have sixteen dollars

(10 - 2) X 2 = 16

I had ten dollars. I told Jimmy I would double what he takes. Jimmy took 2 dollars. I have six dollars.

10 - 2 X 2 = 6



What is happening is happening. The numbers we choose to represent what is happening have to be agreed upon so that we can communicate. Just as we agree on what the word tree means.

@Rolexeo no, it is based on how it relates to real world physics

If you use a smaller number vs a larger one, you can see uf you got the right impact or not

Math isn't originally based in theory. Math is meant to be a representation of the real world, be it having its faults and limits
