This road sign is on westbound I-8 just east of Yuma, Arizona.

The road sign says...

+---------------------------------+ | Avenue 3E US Hwy-280 2 1/4 | | 16th St US Hwy-95 4 | | Weigh Station 4 3/4 | +---------------------------------+the numbers are: 3 280 (2 1/4) 16 4 (4 3/4) the math is: (95 - (280 / 4) + 3) / (2 1/4 + 4 3/4) = sqrt(16) observe... 280 / 4 = 70 95 - 70 = 25 25 + 3 = 28 2 1/4 + 4 3/4 = 7 28 / 7 = 4 sqrt(16) = 4Paul Dickson once said... "When working toward the solution of a problem, it always helps if you know the answer." Caution should always be exercised when using the word

always.The following is a solve for 'n' exercise.

the math was: (95 - (280 / 4) + 3) / (2 1/4 + 4 3/4) = sqrt(16) solve for n : (95 - (280 / 4) + n) / (2 1/4 + 4 3/4) = sqrt(16)
