Wow. In America, trades people use a chart to look up literally anything that requires math. If you’re lucky.

Most of the time “it looks good enough” is enough.

I've had an economics teacher in the Netherlands who had interest tables and wanted us to them too. For those before calculators, those are tables that list the years on the left, and the interest on top, and then the multiplier in the table.

So, 10 years at 6.5% = 1.877

This was in 2005i sh.

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

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