I just have one, hopefully simple, question.

How do you copy and use previous answers? The "Ans" key only allows you to obtain the answer for the previous problem. How do I obtain answers from like 3 or 4 problems ago?

Let me give you a simple example to illustrate my question.

100/83

1.204819277

5x3

15

9x

**1.204819277**

And lets say, I have a new problem and I want to use 1.204819277. "Ans" key would only allow me to obtain 15. Is there a simple way to get 1.204819277 for a new calculation w/o having to retype it manually? TI's let you just highlight the 1.204819277 and press enter and it is copied onto the latest problem. Is this kind of feature available on the Prizm?

Thanks in advance for any type of advice. Let me know if my question is unclear.
