Thanks! Usually adding and division. For example "7 3/4 plus 8 1/8" or "15 3/4 divided by 4." Fractional result would be ideal. I don't know if a sliderule is

  I think a slide rule isn't going to help much... You'll still need to do the addition, and then you'd need to eyeball 15 3/4 as a number between 1 and 2, do the division, and then eyeball the result into a fraction. I think I've only seen decimal marked slide rules, you could certainly have a fraction marked rule, but it wouldn't be that helpful, because 15 3/4 is not easy to turn into 10 * (1 + 1/2 + 3/4 * 1/5 ) And then you're not at a power of two fraction anymore either. Some other tool would be better; probably a pocket calculator that's taken advantage of half a century of computational advances and can manage fractions.

    Yeah, there's a ton of perfectly good fractional calculator apps and so on out there. I was just looking for an excuse to use my dad's old thing. Thanks again for the explanations.

  No. A slide rule is all scientific notation (2 or 3 significant digits on the rule and you carry the mantissa in your head). Very good for accuracy but not so much for precision.
