Nah, I get it. I have a streak of stubbornness, too. Just saying, in this specific case, the odd way to do it has real, genuine advantages and isn't just odd for the sake of being odd. It's not so much an opinion as a philosophy.
If the opportunity arises, I urge you to try making yourself use it for a few days and powering through it. If that a-ha moment comes to you, it changes how you look at arithmatic in general. Or it may never happen, and that's OK, too.
I did use it, back in the day. But the problem is, I use a calculator too few and far between so every time I had to go through this adaptation again.
Also I tend to avoid arithmetic, I hate maths :) What I would like mainly is a binary/hex converter and the ability to do some shifting and XORs etc.
