+--------------------+ | 7th St 1 | | 7th Ave 2 | | 19th Ave 3 | +--------------------+the numbers are: 7 1 7 2 19 3 the math is: (19 - 7 - 7 + 1) / 2 = 3 more math: sqrt(7 + 7 + 19 + 3) = (1 + 2)! more math: 1 + 2 + 3 + 7 = sqrt(summation(7, 19)) * summation(7, 19) = 7+8+9+10+11+12+13+14+15+16+17+18+19 = 169 rsPiEval: (19 + 3) / (7 * 2 - 7 * 1) ~= Pi * 22/7 approximates Pi rounded to nearest hundredth (3.14) * 3.1415926535897932384626 rsPiEval: (2 * (19 + 3)) / (7^1 + 7) ~= Pi * 44/14 approximates Pi rounded to nearest hundredth (3.14) rs42Eval: 7 + 19 + summation(3, 7) + 1^2 = 42 * 42 is the "Answer to Life, the Universe, and Everything" * summation(3, 7) = 3+4+5+6+7 = 25 rsStateEval: sqrt(summation(3, 7))! / 2 - 19 + 7^1 = 48 * Arizona was the 48th state admitted to the Union.
