Question 458018
If you are dealing with large numbers, how long should your number line be.
----
It's not how long your line should be.  It's how you scale your line.

Pick a point on any line segment.
If you pick a point 1 in to the right you could label is 1 or
you could label it 1 million.  It's up to you do decide.
Cheers,
