I usually try doing it in my head first. I use paper if it is available. I use a calculator when I don’t have time, or fail at the first two steps.
I noticed my number skills were deteriorating without proper use, and I found that alarming. I’m still weaker than I used to be, but not as bad as I was.
It’s just important to think for ones self when one can. The brain is a muscle that atrophies without use.
Do you use a calculator?
Slide rule
Abacus
Beans in a clay pot
Fingers and toes

Maybe you number skills are fading because you waste your time and energy on pointless computations. Maybe they just fade with time…
This is anti-scientific. But again I don’t think doing multiplication problems is really going to help anything.
