Solution 12172: Using the Ans() function on the TI-89 Titanium and Voyage™ 200 Graphing Calculators.
How do I use the ans() function on the TI-89 Titanium and Voyage 200 graphing calculators?
The ans() function returns a previous answer from the Home screen history area.
If an integer is used as an argument, it will specify which answer to recall. The valid range of integer that can be used is 1 to 99 and cannot be an expression. The default is one, representing the most recent answer.
• ans() [ENTER] will return the most recent answer.
• ans(10) [ENTER] will return the 10th most recent answer.
