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 Algebrawas 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## Update::2013.10.26

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