The digits of any product of 9 and another number will add up to a product of 9.
e.g. 9 * 8 = 72; 7 + 2 = 9
Let's say you want to find 9*8. Hold your hands in front of you, and count off fingers starting at the left side until you get to 8. Put the eigth finger down, and you are left with 7 fingers and 2 fingers, 72. It obviously won't work after 9*10.

Figured that out one day during Junior year of college in Intro to Business Statistics.
I figured it out in 7th grade. A friend had to identify a sequence of numbers and I noticed that trend.

Las Vegas is further west than Los Angeles...
According too...? Are you getting into the difference between magnetic and true North?
Tucson was once the state capital of Arizona (as was Prescott).
In February 1992, DL and AS flew nonstop on TUS-LAX, CO and UA flew nonstop to DEN, and AA had a red-eye to DFW that left TUS at 2AM and arrived at 5AM. (Found a Flight Guide from Feb. 1992 in the U of A library with a study done in the mid-80's about airports in the Tucson area. They were both very interesting.)
