This no parking sign was found at Lowell School on Old Douglas Road in Bisbee, Arizona.

The no parking sign says...

+---------------------------+ | NO PARKING | | Daily 7:15am to 7:45am | | Monday 11:00am to 2:15pm | | Tues-Fri 2:30pm to 3:00pm | +---------------------------+The math in this "no parking" sign is plentiful so MathBabbler opted to turn the sign into a Pi sign.

: is used as a delimiter the numbers are: 7 15 7 45 11 0 2 15 2 30 3 0 the Pi math is: (30/15) + (45/15) + sqrt(11 - 0! - 0!) + 2 + 2 + 3 + 7 ------------------------------------------------------ = Pi 7 observe... 30 / 15 = 2 45 / 15 = 3 0! = 1 [by definition] sqrt(11 - 0! - 0!) = sqrt(9) = 3 numerator = 2 + 3 + 3 + 2 + 2 + 3 + 7 = 22 22 / 7 = Pi (3.14 rounded to nearest hundreth) [exercise] Sort the numbers in ascending order and calculate the mean, mode, median of the numbers. [exercise] The set of numbers contain two 7's. If the sum of the two 7's is used in the denominator of a fraction that approximates Pi, then the remaining numbers must be arithmetically manipulated to evaluate to what value for the numerator?## Related BARS
