BARS::Jct. Loop 101 on Eastbound Loop 202 in Tempe, Arizona

This road sign was seen while walking on the north-side of the Town Lake in Tempe, Arizona. No math was found in the road sign; however, it was observed that the road sign is on eastbound Loop 202.

The road sign and highway signs say...

   +---------------------------+    +------+
   | Scottsdale Rd         1/2 |    | EAST |
   | McClintock Dr       1 1/4 |    | Loop |
   | Jct Loop 101        2 1/4 |    |  202 |
   +---------------------------+    +------+

   the numbers are:  (1/2)  (1 1/4)  (2 1/4)  101  202

   the math is:  101 * (((2 1/4) - (1 1/4)) / (1/2)) = 202

   observe...
      2 1/4 - 1 1/4 = 1
      1 / 1/2 = 2
      101 * 2 = 202

   more math:  101 * sqrt((2 1/4) + (1 1/4) + (1/2)) = 202

   observe...
      2 1/4 + 1 1/4 + 1/2 = 4
      sqrt(4) = 2
      101 * 2 = 202

   more math:  101 / sqrt((1 1/4) - (sqrt(2 1/4) - (1/2))) = 202

   observe...
      sqrt(2 1/4) = 1 1/2
      1 1/2 - 1/2 = 1
      1 1/4 - 1 = 1/4
      sqrt(1/4) = 1/2
      101 / 1/2 = 202
Exercises

This BARS was created while a Beginning Algebra was in progress and it was used as an exercise for solving equations.


   Solve the following equations for n.

   a) 101 * (((2 1/4) - (1 1/4)) / n) = 202

   b) sqrt((2 1/4) + (1 1/4) + (1/2)) * n = 202

   c) n / sqrt((1 1/4) - (sqrt(2 1/4) - (1/2))) = 202

I went to my daughter's race on 10/20/2013 and ended up below these signs.
