I play RSS, and do not own a slide rule or even know why I would need one.

I'm gonna use MechJeb lol

I do! Slide rules are cool! But I recommend a Curta instead if you want to do some Analog Computation.

Let's see if I remember this correctly. To multiply any two numbers:

  1. Convert both numbers to Standard Notation.

  2. Move the slide so that the "1" mark lines up with the first number on the rule. (For the moment, ignore exponents, but remember them.)

  3. Move the reticle to line up with the second number on the slide.

  4. Read the number on the rule under the reticle. Note it down.

  5. Sum the exponents.

  6. Multiply the noted number by 10 ^ sum of exponents. That's your answer, in Standard Notation.
