This calculator is far better than the old one, you can use negative numbers as well as reset the calculator and in my opinion, a much better interface. And again I did all of this by myself without any outside help.
Steps: 1. The calculator will ask you what number you want type, lets pick -25 for this example. 2. Click the check mark or enter. 3. Now that you have selcted your number, operations will light up green which means you can use them now. 4. I will click the button with Division symbol "/". 5. Now that it has been clicked it goes back to normal with all of the other buttons. 6. type the second number, I will do 5 for this example 7. Click the check mark or enter. 8. We have input -25 / 5 which equals -5
