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.

I wish to convey my gratitude to you and, especially , Peter, who patiently and pleasantly took time out to remedy the problem. Thus Educalc was my last resort! Again, THANK YOU VERY, VERY MUCH!!!!
