Not related to the monopoly stuff but I like HP calculators best! For college I used an HP 35S—it’s a programmable scientific calculator and fun to program because it uses RPN stacks for calculations and storing results.

I had to hunt online for a used HP when I took a college class in 2003(ish) because the final exam needed a calculator and I honestly had no idea how to use non-RPN (I'm sure I could have figured it out, but been much slower).

I'd been using RPN since high school.

I feel the same way. I typically use "dc" for all my calculation needs. I recently needed to do some calculations on my phone and was very confused that it "knows" the order of operations. I already knew what order I wanted the operations performed in, thankyouverymuch.

2 + 3 * 9 = 29 but 2 3 + 9 * p = 45, for example. Apparently you have to press = every time you want to use the sub-result in the next calculation. It is very confusing.

I am not sure why we even have infix operators in mathematics to begin with. It just causes problems.
