Absolutely. But I learned in 2005, and the electric calculator had replaced the sliderule a couple of decades earlier.

But this is something they were great at, but usually not with the same accuracy. It's hard to get more than 3 decimal places out of one, and tables are great for that, you can fill whole books with them.

In my study time it was the only which exists, still no electronic or computers , only in big companies, which worked with punch cards.

I would use an Abacus for multiplication and a Venier scale for accuracy
