hi,

i'm new and i'm currently taking visual logic programming course at my local college and well i know this is probrable a very easy problem but i need help i've never been good in math and it's frustrating that i can't seem to figure this out!!! anyway i need help creating a flow chart where i input two values and it displays their positive difference for ex. if the first input is 6 and the second input is 9 then the positive difference is 3. likewise, if the first input is 9 and the second input is 6 the output is still a positive 3.


it sound simple and i just know if i can get at least a little help then maybe my brain will light up!!!!

I think your looking for something like this:

1 INPUT A 
2 INPUT B
3 IF A - B < 0 THEN GOTO 6
4 PRINT A - B
5 END
6 PRINT B - A 
7 END

So if A = 9 and B = 6 then you will get 3. If A = 6 and B = 9, then A - B would equal a value less than 0 (negative), thus telling the program to reverse the numbers to B - A which will equal 3.

This is a great answer! I like the basic/assembly style of writing the visual logic code and it does a great job of presenting the logical flow. I will use this style for any future visual logic questions.

Or just:

abs(A-B)

abs is the standard convention for absolute value.

Can you explain the above asnwer some more i'm trying to use it but my output keeps getting errors any reasons why?

There would be no need to compare against a zero though. Would it not be more sufficient to test it against itself. Eg.

3 IF A > B THEN GOTO 6
