what's this number?

That would be the total number of miles between NAVAIDs on the airway.

Didn't know that!
Why do I need to know how many miles to NAVIDs and in which direction?

Useful if you have something that gives miles to navaid like DME or GPS.

It's an aid to flight planning if you plan to follow airways - you wouldn't need to measure each individual segment, you could just add up the numbers.
Not that useful anymore, though. But in the days of paper sectionals and plotters, it could help a little.
Here's a more useful number on sectionals you may never notice if not pointed out.
At a quick glance you can use this number to see that you need to stay above 1700 to avoid the 1500+ foot tower if you fly through this area.

Yes, if it's a man-made obstacle, you add 100' (for reporting error) and round up to the next 100.
If it's terrain, there's a 300' aggregate pad and then the round up.

seriously, there are a number of reasons. Remember the world is not only about GPS. So, among other things, it is an aid to situational awareness. And since VORs have a service volume, it will help explain why you are losing the signal from one and should be switching to the VOR at the other end,
