Psion Teklogix netBook, 32M/64M manual Re-using answers and calculations, Using the memories

Re-using answers and calculations

In the Scientific view you can re-use the answer from your last calculation.

∙To insert the last answer at any point in a calculation: tap the Ans button at the appropriate point. The calculator will insert ‘Ans’ in the calculation line, representing the last result.

∙To start a new expression with the last answer: just enter the rest of the expression as though the answer was already written at the start. The calculator will prefix the expression with ‘Ans’.

You can also re-use and edit calculations you have performed earlier. This can save time if you want to perform a new calculation which differs only slightly from a previous one.

∙To re-use a previous expression: use the up and down keys, or the Edit previous and Edit next commands on the Edit menu, to display the last 10 calculations one by one on the calculation line. When you find the expression you want to re-use, change it if required and proceed as normal.

Note: The value of Ans used in a calculation will always be the value of the last calculation. If you re-use a calculation based on a value of Ans, the result will be calculated using the current value of Ans rather than the value at the time of the original calculation.

Using the memories

The Scientific calculator has 26 memories, labelled A through to Z. You can assign a value to each of these memories, and then incorporate the names into expressions.

To assign a value to a memory:

1.Enter the number to be stored. If the calculation line is displaying an unsolved expression, the stored value will be the RESULT of the expression.

2.Tap –>, or select Assign to from the Memories button on the Toolbar or the command on the Tools menu.

3.Type the memory name. As memory names must be entered as a capital letter, you will probably need to hold down the shift key and type the letter key for the memory name.

Note: You can also assign a value to a memory by tapping the Mem button, highlighting the memory to use and then tapping the Assign to button in the dialog.

∙To display the contents of the memories: tap the Mem button, or select Show all from the Memories commands on the Tools menu.

∙To use a stored number in a calculation: type the capital letter corresponding to the memory at the appropriate point in the calculation. Alternatively, tap the Mem button to display the list of memories, highlight the memory you want and tap Select.

Note: You can assign values to the memories in any order you like, so use the names as a reminder of the information they contain. For example, use the T memory for a rate of taxation, Y for the rate of exchange into yen and so on.
