Suggestion for a challenge

Question

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.

Answer 1

Please change this from a question to a discussion =)

Great challenge BTW!

Answer 2

Not 8-digit but how about BQJ710-0 ?

And I know another calculator KWR934 by Alex_2000 which is listed in an article "Small Basic Program Gallery" of Small Basic Blog. 

Or you mean your challenge need hand write recognition?

I think he means to do the calculations like this for example:

Oh, I understand.  That's interesting.  I love it.  In Japan, we do division as follows.  How about you?

That's exactly how we Americans do it.

Answer 6

Yep! I guess the same rules apply for all nationalizations?

Answer 7

I noticed that my program Combination(52C4) announced in thread "Calculate with Big Numbers in Small Basic" has similar logic for this challenge.  This program has Mul(), Div(), Minus() subroutines.  I'd like to modify these subroutines to get answer of this challenge.
