So it sems they do not. Speaking of working out a problem without a mechanical device, I passed math class problems in less time using a book of math tables or a slide rule then the ones using a calculator. ANd I hade better scores. As you said, that as 50 years ago.

I dazzled my Grand-daughter when I pulled out an old, old cheap sliderule and did some division of decimals. Admittedly,I had to do some experimenting to be sure my decimals came out correctly. They did to four places. Aw, it was good guessing.

Don't they teach anythig about Roman Numerals in school anymore?
How is Roman Numerals related to this topic? Did you response to some posts?

The camera model was a MIV meaning Mark 4. The 4 is represented by the Roman Numeral “IV” or did you not learn Roman Numerals either?
Yes I “responded” to other posts.
I also try to proofread my responses.

I didn't know which post your responded to. I do know IV is 4 but really I don't know much about Roman Numerals. How would you do math with them? I can do math in my head, pencil and paper, abacus, slide rule, calculator but don't know how to do it with Roman Numerals.

I wasn’t referring to doing math with them, just recognizing the use of them as a designator for the model.

You can do math with them, but it is complicated. For one thing, there are no zeroes. The letters are I,V,X,L,C,M: values, i, 5, 10, 50, 100, 1000. Higher values would have a bar over them. Smaller number before larger, subtract that from larger. Smaller number after larger, add to larger. So, IV=4: VIi=7: XL=40: LX=60. As a rule four I's were seldom used save for clocks long after Rome was on the decline. I hope I didn't go too far with this. If I did, blame my old job....teacher
