Left vs. right side arithmetic keys

[johnb]

I find that the difference between operators on the left versus the right don't throw me nearly as much as the difference between "-+×÷" and "÷×-+" does.

I generally am looking at the calculator when I'm operating it, so that probably accounts for left/right. (I'm left handed... and I also have a bad habit of looking at my fingers when I'm playing piano or organ --- LOL, when playing Theatre Organ, if you don't already know the music by heart when doing registration changes and such, you're already sunk!)

Most of my machines are Voyagers, Pioneers, or 48's. (And a 35s which follows the Pioneer pattern... roughly.) So when I'm using one of the classics, I'm always dividing when I meant to add, and so forth. Why doesn't my eye pick up on the operator before my finger gets there?


PS: To muddy the analytical waters more, I'm a touch typist and don't even have to look down for punctuation like []{}\\// and so forth. So, go figure!
