Small Basic Featured Thread – Suggestion for a challenge: Calculations by Hand

This is not so new thread but I love this one: Suggestion for a challenge by jherch77 in Small Basic forum.

I would like to make the following suggestion for a challenge:

Create a fully functional calculator (8-digit, basic calculator, not scientific) but do all the calculations by hand…meaning that if the user wants 356 * 8…the program should multiply 8*6 then 8*5+4 then 8*3+4. Just like you would do it if you had to multiply with pencil and paper. This would require addition, subtraction, multiplication and division and as an added challenge, negative numbers.

I wrote the first beta program for division by writing: PHW347.

This program can calculate correctly only special cases.  I’m going to rewrite this program to more generic cases.

Thank you jherch77 for your challenge!
