The highway signs say...

+------+ +---------------+ | 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) / 10_{2}= 10 [solve for 10_{2}] (90 - 70) / 10_{2}= 10 more number system math: sqrt(sqrt((90 + 70) / 10)) = 10_{2}Note: These highways signs were not accepted by RoadSignMath.com because the signs are not all attached to a single gantry (pole).
