These road signs were found on the Loop 101 looking north from Baseline Road.

This BARS will not be submitted to RoadSignMath.com (RSM) because the math for these signs contain deductions with respect to the RSM scoring system. For example, the following operations are frowned upon when doing road sign math.

a - a = 0 a x 1 = 1 a x 0 = 0 a / a = 1In addition, RSM does not use the

`ceil()`

and`floor()`

functions.The road signs say...

+-----------+ +----------+ +----------+ | | | Exit 55A | | Exit 55B | | 101 North | | 60 West | | 60 East | | | | Phoenix | | Globe | +-----------+ +----------+ +----------+ the numbers are: 101 55 60 55 60 the math is: 60 + 101(55 - 55) = 60 ...or... 60 x 101^{(55 - 55)}= 60 ...or... 60 x log(sqrt(101 - 55 / 55)) = 60 ...or... 60 x log(sqrt(101 - (55 - 55)!)) = 60 ...or... floor(sqrt(101)) = 60 + 60 - 55 - 55 evaluate left-hand side: sqrt(101) = 10.05 floor(10.05) = 10 evaluate right-hand side: 60 - 55 + 60 - 55 = 10 ...or... ceil(sqrt(summation(55, 101) - (60 - 55)!)) = 60 60 - 55 = 5 and 5! = factorial(5) = 120 summation(55, 101) = 3666 3666 - 120 = 3546 sqrt(3546) = 59.548 ceil(59.548) = 60
