Calculator

This calculator uses scoreboard commands to add and subtract. Please do not use this device too fast, because it will not work if you rush it. If it doesn't work, hit the clear button. All of the buttons are labeled by name tags. If the output is not right, hit the clear button and try it again. You will find the output on the sidebar when you press the "Equals" button. Anyways, hope you enjoy!

Additional Notes

There is a bug where a number doesn't register. I'll try to fix it as best I can.

Please tell me if anything needs to be changed, or fixed! Also, tell me if there are any bugs.

Give the calculator a second before you press another button.
