Text: Hi Peter, Thanks for the tips! I’m really happy with my purchase of 12CP–it’s such a powerful little thing. Previously I almost bought the Texas Instrument calculator because of HP’s RPN, but I realized that 12CP does Algebraic model as well. Besides, RPN feels natural just after using the calculator for about 1-2 days of perusing the manual and the calculator :) Warm regards, Ray.
