These road signs from Baltimore, Maryland, were taken by "Disney Dan."

The road signs say...

+------------------+ +--------------+ | Exit 7 | | Exit 8 | | MARC Dorsey Sta. | | Coca-Cola Dr | | 1/2 mile | ---------------- -------------------- | Exit Only | | No Trucks | +--------------+ | over 5T GVW | +------------------+the numbers are: 7 (1/2) 5 8 the math is: 7 - 5 = sqrt(8 * (1/2)) more math: 8 - 7 = log(5 / (1/2)) more math: summation(cuberoot(8), 5) * (1/2) = 7 * cuberoot(8) = 2; summation(2, 5) = 2+3+4+5 = 14 rsPhiEval: ((8 - 7) + sqrt(5)) * (1/2) = Phi * Phi is the golden ratio and it approximates 1.61803399 rsStateEval: 7 * (5 - 8 * (1/2)) = 7 * Maryland was the 7th state admitted to the Union. rs42Eval: ((8 - 5) * 7) / (1/2) = 42 * 42 is the "Answer to Life, the Universe, and Everything" off-by-one rsAgeEval: 5! * (1/2) - 8! / 7! = 53-1 * MathBabbler was 53 years young when he found this equation.
