This road sign is on westbound I-8 in Arizona.

The road sign says...

+---------------------+ | Foothills Blvd 5 | | Yuma 19 | | San Diego 196 | +---------------------+the numbers are: 5 19 196 the math is: 19 - 5 = sqrt(196) off-by-one rsCardinalityEval: sqrt(196 - summation(5, 19)) = 3+1 off-by-one rsCardinalityEval: sqrt(sqrt(196 - summation(5, 19))) = 3-1 off-by-one rsCardinalityEval: cuberoot(sqrt(196) - (5! % 19)) = 3-1 * There are three numbers in this road sign. * summation(5, 19) = 5+6+7+...+17+18+19 = 180 off-by-one rs37Eval: 5 + 19 + sqrt(196) = 37+1 off-by-one rs37Eval: (19 % 5)! + sqrt(196) = 37+1 * Whyrs37Eval? 37 Heaven @ http://thirty-seven.org off-by-one rsAgeEval: 196 - 5! - 19 = 56+1 * RoadHacker was 56 years young when he found this road sign. BARSfunc math: mult_digits(19) + 5 = sqrt(196) * mult_digits(n) = product of the digits of n domain: n must be a prime number * 19 is prime; mult_digits(19) = 1*9 = 9## Update::2015.08.30

This BARS was updated after MathBabbler found out that the number 196 was the smallest Lychrel Number.

the numbers are: 5 19 196 rsHwyEval: sqrt(196) - 5! % 19 = 8 off-by-one rsHwyEval: sqrt(196) / sqrt(factorial^{-1}(5 + 19)) = 8-1 * This road sign is on I-8. off-by-one rsAgeEval: 196 - 5! - 19 = 58-1 * MathBabbler was 58 years young when he updated this BARS.

Note: This was MathBabbler's 800th BARS (BAB# 3774).
