This road sign was found on westbound I-10 in Phoenix, Arizona.

The road sign says...

+-------------------+ | 7th Ave 3/4 | | 19th Ave 1 1/2 | | Jct 17 2 | +-------------------+ the numbers are: 7 (3/4) 19 (1 1/2) 17 2 A C ---------------- ------------- | | | | the math is: (2 x ((3/4) / (1 1/2))) + sqrt(19 + 17) = 7 | | ----------------------- B observe... A = (3/4) / (1 1/2) = (3/4) / (3/2) = (3/4) x (2/3) = (1/2) B = 2 x A = 2 x (1/2) = 1 C = sqrt(19 + 17) = sqrt(36) = 6 B + C = 1 + 6 = 7
