A game with calculators... yes please

This weekend, we’re playing a multi-evening game of Cashflow. Calculators are handy when finances become more involved. Interestingly, the three of us have different calculator preferences.

My wife likes the large keyboard numpad style (muscle memory), and my son has spent a bazillion hours on a TI-84.

I don’t know how to use a non-RPN calculator, so my choice is obvious.
