The road sign says...

+-----------------+ | I-10 15 | | Lordsburg 25 | +-----------------+the numbers are: 10 15 25 the math is: 10 + 15 = 25 more math: 15 - 10 = sqrt(25) more math: 25 % 15 = 10 more math: 15 % 10 = sqrt(25) more math: summation(log(10), 15)) = sqrt(25)! * summation(1, 15) = 1+2+3+...+13+14+15 = 120 rsRomanNumeralDigitEval: (10 + 15) / 25 = I rsRomanNumeralDigitEval: log(sqrt(summation(10, 15) + 25)) = I * summation(10, 15) = 10+11+12+13+14+15 = 75 off-by-one rs42Eval: log(10) + 15 + 25 = 42-1 * 42 is the "Answer to Life, the Universe, and Everything"
