Recycle Previous Answers and Entries with the TI-84 Plus Calculator

One of the benefits of using the TI-84 Plus calculator is that it has a better memory than you do. You can use the previous answer in the next arithmetic expression you want to evaluate, and you can reuse the last command, function, or expression entered in the calculator.

Use the previous answer with the TI-84 Plus

If the previous answer is to appear at the beginning of the next arithmetic expression you want to evaluate, first key in the operation that is to appear after the answer. The calculator displays Ans followed by the operation. Then key in the rest of the arithmetic expression and press [ENTER] to evaluate it.

If you want to embed the last answer in the next arithmetic expression, key in the beginning of the expression to the point where you want to insert the previous answer. Then press [2nd][(-)] to key in the last answer. Finally, key in the rest of the expression and press [ENTER] to evaluate it.

Recycle the last entry with the TI-84 Plus

If you want to reuse the last command, function, or expression entered in the calculator — but with different instructions, arguments, or variables — you can simply recall that command, function, or expression and then edit it. To do so, follow these steps:

  1. Enter the command, function, or expression on the Home screen and then press [ENTER] to execute command or evaluate the function.

  2. Press [2nd][ENTER] to paste a copy of that command or function on the home screen.

  3. Edit the command, function, or expression and then press [ENTER] to reevaluate it.
