did studying ur calculator manual help learn Quant?

has anybody else found that after studying your calculator manual helped you to understand quant better when you first started reading it?

I didn’t found the Manual helped me with the concept, but helped me with some calculation Q, some feature will takes much less time than the method taught in notes and text book . It’s worth a few hours on manual.

yes Data sheet/Stat is very useful on the TI BA II, so learn how to use those

i found it to be the other way around, studying quant helped me learn how to use my calculator
