Here's a good example for everyone. I think this may be a major point too.
Say you travel 3 miles north to work (+3). After 8 hours, you travel 3 miles south back to home(-3).
Where did you end up (relative to starting point)? 0 miles away
How far away did you travel? 0 miles away
What was the total distance traveled? 6 miles away
You have traveled 6 miles, yet your position in space is 0, because you returned to your starting location. 6 != 0 yet you traveled both 6 miles and 0 miles. Can everyone understand where I'm coming from now?
Interesting theory, but as a software engineer I have to both disagree, and provide counterpoints
Your entire presentation is based off a specific point of view, as well as a frame of reference for the data. Using programming (and thus, basic math), you can say the following:
(1-1) == 0;
So, if we subtract 1 from 1, we are left with 0. Now, if zero was not a number, that would not be possible, as you can't jump from numbers to any other form of data storage without some conversion happening.
With your travel example I have quoted, yes the distance traveled is 6 miles, but right before that you ask:
Where did you end up (relative to starting point)? 0 miles away
This is a different question involving the data than your following question:
What was the total distance traveled? 6 miles away
These are two very different questions using the same scenario. Consider that you are 6 miles from work and plan on driving it (to be consistant with your above example). We have three pieces of data.
Location A: Starting point.
Location B: Ending point.
Distance to travel: 6 Miles (OR A - B)
When you start, you are 6 miles from your destination, 0 Miles from the starting point. Half way there, you are 3 from each, (making your median point 0 as an aside), and when you arrive, you are 0 miles from your destination, but 6 miles from the start. All pieces of data are accurate, but provide a different view of the situation.
