   +------+  +---------------+
   |  TO  |  | WEST Business |
   | I-10 |  |   Loop I-10   |
   +------+  +---------------+
   +-----------+ +-----------+
   | US Hwy-70 | | NM Hwy-90 |
   +-----------+ +-----------+
   the numbers are:  10  10  70  90

   the math is: 10 + 10 + 70 = 90

   [solve for 'n']  n + n + 70 = 90

   number system math:  (90 - 70) / 102 = 10

   [solve for 102]  (90 - 70) / 102 = 10

   more number system math:  sqrt(sqrt((90 + 70) / 10)) = 102

Note: These highways signs were not accepted by RoadSignMath.com because the signs are not all attached to a single gantry (pole).

   rsHwyEval:  log(sqrt(sqrt(90 * 10) + 70)) * 10 = 10
   * These highways signs were found on Business I-10

   rsHwyEval:  sqrt((10 + 10 + 70) * 90) = 90
   * These highways signs were found on AZ Hwy-90
