Printing Calculator
A calculator that keeps a running tape of your calculations, just like a classic printing calculator.
What is a Printing Calculator?
A printing calculator, also known as a tape calculator or adding machine, is a calculator that provides a running log of all entries and calculations on a paper tape or, in this case, a digital "tape". This core feature allows users to review their steps, check for errors, and keep a verifiable record of their work, which is invaluable in many financial and bookkeeping tasks.
How to Use This Calculator
Using this calculator is designed to be intuitive, just like a standard desktop calculator. Use the number pad for input and the operator buttons (+, -, ×, ÷) to perform calculations. When you're ready for the final answer, press the equals (=) button. To clear everything and start fresh, use the 'AC' (All Clear) button. As you perform your calculations, every number you enter and every operation you perform will appear on the virtual "Tape" on the right, which you can scroll through to review your work at any time.
