Last time I made a calculator, it was just purely an adding only machine with a limit of 255 called the 8B01. But now, I stepped forward into improving the calculator into a better design which allows it to both adds and subtracts numbers, all in 8-Bit in one single machine only slightly larger than the 8B01, which is called the 8B02.

If you want to understand how to use it, then it has a manual where it shows how to use it, and if you don't understand binary, then in the manual also will show you the basics of binary, where it tells you how to input and read numbers in binary.

I was going to make it 16 bit, but then I thought that it would be unnecessary since it will double the size of the calculator, and the 255 number limit is enough to do basic addition and subtraction math. Once I add Multiplication and division into the calculator, then I might consider upgrading to 16 bit.

Anyways Enjoy! :)
