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. A showerthought should offer a unique perspective on an ordinary part of life.

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?

PEMA is technically correct. Division and subtraction are illusions.

Actually multiplication and division are shorthand notations for addition and subtraction - e.g. 2x3=2+2+2 - so everything boils down to addition and subtraction.
