This road sign is on NM Hwy-6563, which is used to get to the National Solar Observatory in New Mexico.

The road sign says...

+-----------------------+ | Sacramento Peak 6 | | Timberon 20 | | Bluff Springs 4 | +-----------------------+the numbers are: 6 20 4 the math is: summation(sqrt(4), 6) = 20 * sqrt(4) = 2; summation(2, 6) = 2+3+4+5+6 more math: 20 % 6 = sqrt(4) more math: gcf(6, 20) = sqrt(4) off-by-one math: 20 / 4 = 6 - 1 off-by-one rsStateEval: 6 + 20 * sqrt(4) = 47 - 1 * New Mexico was the 47th state admitted to the Union.
