### BARS::Water Well Sign at Gaicki Park in Tempe, Arizona

This water dept. sign is located at Gaicki Park in Tempe, Arizona.

The water dept. sign says...

```   +--------------------------+
|     City of Tempe        |
|       Water Dept.        |
|       Well No. 11        |
| Well ID. A(1-4) 1 C6B-11 |
|     PWS # 0407-100       |
|       55-514694          |
|     Emergency No.        |
|     480-350-2669         |
+--------------------------+
```
```   the numbers are:  11 1 4 1 6 11 407 100 55 514694 480 350 2669

the math is:
A = sqrt(2669 - 407 - sqrt(514694 + 480 + 350) - 11 - 11 - 1)
B = 55 - ((100 - 4) / 6)
A / B = 1

observe...
A:  514694 + 480 + 350 = 542524
sqrt(542524) = 718
2669 - 407 - 718 - 11 - 11 - 1 = 1521
sqrt(1521) = 39
A = 39
B:  100 - 5 = 96
96 / 6 = 16
55 - 16 = 39
B = 39

The numbers 2669, 407, 514694, 480, 35, 11, 11, 1 are used
to calculate A and A equals 39.

the numbers are:  39  55  100  4  6  1

Phi math:  (log(sqrt(100)) + sqrt(1 + 4)) / (6 - sqrt(55 - 39)) = Phi

observe...
Phi = golden ratio = 1.61803399
sqrt(100) = 10
log(10) = 1
sqrt(55 - 39) = sqrt(16) = 4

Pi math:  (16 + 6) / ((4 - 1)! + log(sqrt(100))) = Pi

observe...
Pi = 3.14  [rounded to nearest hundreth]
```

Important Note: It is not clear what the Well ID is. The '6' in C6B-11 might be a 'B'. This sign was initially interpreted by looking at the picture on the digital camera, which has minimal zooming capabilities. Upon reviewing the sign on a computer monitor, it appears as though the Well ID is CBB-11; i.e., if the sign doesn't contain a '6', the all of the aforementioned math, while arithmetically correct, is invalid.

##### The Math Without the Number 6
```   +--------------------------+
|     City of Tempe        |
|       Water Dept.        |
|       Well No. 11        |
| Well ID. A(1-4) 1 CBB-11 |
|     PWS # 0407-100       |
|       55-514694          |
|     Emergency No.        |
|     480-350-2669         |
+--------------------------+
```
```
the numbers are:  11 1 4 1 11 407 100 55 514694 480 350 2669

A = sqrt(2669 - 407 - sqrt(514694 + 480 + 350) - 11 - 11 - 1) = 39

the numbers now are:  55  100  4  1  A=39

the math is:  sqrt(100 / 4) - sqrt(55 - 39) = 1

observe...
100 / 4 = 25
sqrt(25) = 5
55 - 39 = 16
sqrt(16) = 4
5 - 4 = 1

Phi math:  (1 + sqrt(sqrt(100 / 4))) / sqrt(sqrt(55 - 39)) = Phi

Pi math:  ???
