These highway signs are at the New Mexico border in Texas.

The highway signs say...

+-------+ +-------+ | East | | Texas | | US 82 | | 769 | +-------+ +-------+the numbers are: 769 82 sum_digits(769) = 22 split_into_squares_sum(82) = { 49, 25, 4, 4 } the numbers become: 22 49 25 4 4 the math is: 4 / (49 - 25 - 22) = sqrt(4) Note: 769 is prime and so is reverse_digits(769)The picture in this BARS was taken during the summer of 2001. MathBabbler started doing BARS during May of 2005.

These highway signs became a BARS after the

`and`

sum_digits(n)`functions were created.`
