The road sign says...

```   +-------------------+
| Jct U.S. 70    36 |
| Globe          39 |
+-------------------+

the numbers are:  70   36   39

```

This road sign was found heading south on AZ Hwy-77 in Winkelman, Arizona.

The road sign says...

```   +-------------------+
| Mammoth        20 |
| Jct SR 79      43 |
| Tucson         68 |
+-------------------+

the numbers are:  20  43  68  79

the math is:  no math found
```

The merged (or combined) road signs say...

```   +-------------------+   <-- heading north on AZ Hwy-77
| Jct U.S. 70    36 |
| Globe          39 |
+-------------------+
+-------------------+   <-- heading south on AZ Hwy-77
| Mammoth        20 |
| Jct SR 79      43 |
| Tucson         68 |
+-------------------+

the numbers are:  70  36  39  20  43  68  79

that math is:  sqrt(sqrt(36 - 20))^sqrt(79 - 70) = sqrt(68 - (43 - 39))

observe...
evaluation of the left-hand side:
36 - 20 = 16
sqrt(16) = 4
sqrt(4) = 2
79 - 70 = 9
sqrt(9) = 3
2^3 = 8
evaluation of the right-hand side:
43 - 39 = 4
68 - 4 = 64
sqrt(64) = 8
