With CALC 1 you can use the classic 10bii or 12 that you are familiar with, then when you need more, just navigate to any of the over 100 CALC 1 calculators!  Switching between the calculators is easy since the stack, TVM and storage registers values are shared.


For example, use either of the classic calculators to calculate a payment, then use the CALC 1 amortization calculator for a  table or graph without have to re-enter the data.  CALC 1 has currency conversion, UOM conversions, easy to use Forms for TVM, Depreciation and Bond calculation and so much more!
