These highway signs were on eastbound US Hwy-60 in Globe, Arizona.

The highway signs say...

+-------+ +-------+ | East | | East | | US 60 | | US 70 | +-------+ +-------+ +-------+ +-------+ | North | | South | | AZ 77 | | AZ 77 | +-------+ +-------+the numbers are: 60 70 77 77 the math is: log(70 - 60) * 77 = 77 observe... 70 - 60 = 10 log(10) = 1These signs cannot be submitted to RoadSignMath.com because RSM discountinued allowing the

`log()`

function during April of 2006.MathBabbler supported this change by RSM because the

`function comes with a free`

log(n)`. To do`

10`, a`

log_{y}nyis needed, but`does not require a ten.`

log(n)BARS will continue to use the

`and`

log(n)`functions.`

ln(n)## Update::2008.04.30

During late-April, 2008, MathBabbler created the

`function.`

split_into_squares_sum(n)the numbers are: 60 70 77 77 split_into_squares_sum(77) = { 64, 9, 4 } the numbers become: 60 70 77 64 9 4 the math is: 70 - (sqrt(77 + 4) - sqrt(64) + 9) = 60 observe... 77 + 4 = 81 sqrt(81) = 9 sqrt(64) = 8 9 - 8 + 9 = 10 70 - 10 = 60 This is a RSeval because the highway signs are on US Hwy-60.
