This road sign was located 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: floor(summation(68, 79) / 43) = 20 observe... summation(68, 79) = 882 882 / 43 = 20.51162790 floor(20.512) = 20 ...or... truncate(20.512, 0) = 20 rsHwyEval: 79 - sqrt(20 / sqrt((68 - 43))) = 77 This road sign is on AZ Hwy-77. observe... 68 - 43 = 25 sqrt(25) = 5 20 / 5 = 4 sqrt(4) = 2 rsAgeEval??? expression = 48 This road sign was found when MathBabbler was 48.## Update::2008.05.05

The following math was inserted after the

`function was created during April of 2008.`

split_into_squares_sum(n)split_into_squares_sum(20) = { 16, 4 } split_into_squares_sum(68) = { 64, 4 } the numbers become: 16 4 36 64 4 the math is: sqrt(79 - 43 + 64) + 4 + sqrt(4) = 16 observe... 79 - 43 + 64 = 100 sqrt(100) = 10 sqrt(4) = 2## Update::2008.05.16

On 1 May 2008, MathBabbler wrote this C++ program to convert a string into a number. The program converts the string into the digits that MathBabbler needs to press on his cell phone in order to send the string as a text message. The number of the string-to-number conversion is the sum of the digits digits needed to send to enter the string as a text message.

mammoth: 6266666844 (sums to 54) sr: 7777777 (sums to 70) tucson: 888222777766666 (sums to 109) jct: 52228 (sums to 19)the numbers become: 20 79 43 68 54 70 109 19 the math is: (20 + 79) - (109 - 19) = (68 - 43) - (70 - 54)
