### BARS::7th Street at McDowell Road in Phoenix, Arizona

These street signs at the corner of 7th Street and McDowell Road in Phoenix, Arizona. [picture taken 6/11/2016]

The street signs say...

+----------------+
| 7th St.  700 E |
| <-- South I-10 |
+----------------+
the numbers are:  7  700  10

the math is: sqrt(700 / 7) = 10

more math:  (700 % 7)! = log(10)

rsCardinalityEval:  log(700 / 7) + log(10) = 3
* There are three numbers in these street signs.

... spf(n) = the sum of the prime factors of n
domain: n must be a composite number
700 is composite; spf(700) = 2+2+5+5+7 = 21

BARSfunc math:  sqrt(7 * 700) / 10 = dup(7)
BARSfunc math:  700 / 7 / 10 = dup(10)
* dup(n) duplicates n enabling it to be used twice

BARSfunc rsCardinalityEval:  cuberoot(spf(700) + 7 - log(10)) = 3
* There are three numbers in these street signs.

off-by-one BARSfunc rs37Eval:  7 + spf(700) + 10 = 37+1
* Why rs37Eval? 37 Heaven @ http://thirty-seven.org

off-by-one BARSfunc rsStateEval:  7 * 10 - spf(700) = 48+1
* Arizona was the 48th state admitted to the Union.
