Arithmetic Demo

Kids grow up doing arithmetic drills. Dozens of them on a worksheet, for days, weeks, months. I did not need THAT many to master my arithmetic.

Kids (and adults), do you know why we do paper-pen methods of arithmetic the way we do them?

Sure we can do 1 digit calculations in our head. But adding a 2 digit by 2 digit gets too hard. We need to break down into pieces and add up the results... and our base-10 system makes it easy to do so.

I want to automate the mundane calculation process. Sure, there is the calculator, a very important invention.

But calculators do the job too fast. The steps are missing.

Here we are: the Arithmetic Demo. Enter your own numbers and see the calculation in process.
Just keep hitting the Next button.
