Best system for calculators IMO. Especially if you need to add many numbers together (eg doing price calculations)—just enter all the numbers to the register, double-check for errors, then add together. Way less error prone than traditional calculators.
Comment on PEMDAS is technically correct, but morally wrong

Reverse Polish Notation works almost like you describe. You put the operands first, then the operation. For example:
- 3 + 4 --> 3 4 +
- 3 • (5 + 2) --> 5 2 + 3 •
Probably the reason why we are not using it is because most tools today use algebraic notation, and it would be a lot of effort to switch

It’s just less readable for humans, great for programs though

I have no doubt that your link goes to urban dictionary.

I loved my HP48GX calculator with RPN.
