As you work, the Talking Calculator speaks each number and operation you enter, as well as the resulting answer.

2.  Choose the operator you want to use.

3.  Enter the next number.  To erase a digit, click the Back button. To erase the entire line, click the CE (Clear Entry) button.

4.  To hear and see the result, click the  =  (equal) button.  From the keyboard, press either the = key or the Enter key.

To erase the entire calculation and start again, click the AC (All Clear) button or press the Esc key.
