  Moves C index to 2 on the D scale Moves indicating line to 2 on the C scale Reads 4 on the D scale

  Good thing 2+2 and 2*2 yield the same answer. Would have to bust out the addiator otherwise

      Yoy can use 2 normal rules to add/rest 2 numbers, but you can’t do it in a slide rule with its logarithm scales.

    Well, but fails with 3+3, there an US engineer must use still an addiator. Nowadays it’s easier with an pocket calculator.

      But a pocket calculator doesn’t get you nearly enough street cred these days

  You could probably do log_10(10²×10²) instead?

    It’s the same as 2*2

  ln(2) + ln(2) = ln(4)

    Try with 3+3
