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.
Could you use a slide rule for that kind of multiplication?

I would use an Abacus for multiplication and a Venier scale for accuracy
In my study time it was the only which exists, still no electronic or computers , only in big companies, which worked with punch cards.
