If we're supposed to be able to understand math as easily as a language, we should be able to read it from left to right like a language.
Yes, I know there's lots other languages that go right to left or top to bottom, but the point is you don't have to go jumping around the page or sentence figuring out which word should be read first based on which characters it contains.
We put the first word first, then the second word second, etc.
Why can't we just write equations in the order they were meant to be solved?

You can if you wrote everything as just addition and subtraction, but then we made some shorthand notations for that, such as 2x3=2+2+2, and so now you have to do multiplication before addition otherwise you get a wrong answer, and if you wrote all multiplications before all additions there'd still be no problem, but as someone else pointed out, there are cases where it's easier to have a different order, and so voila! Order of operations rules.

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted, clever little truths, hidden in daily life.

Here are some examples to inspire your own showerthoughts: 1

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. No politics
    • If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
    • A good place for politics is c/politicaldiscussion
    • If you feel strongly that you want politics back, please volunteer as a mod.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct and the TOS

If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.

Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report the message goes away and you never worry about it.
