The fun title has nothing to do with deriving the solution, sans one exception, see silly hint.
Full disclosure, this is a wee bit of a math puzzle. I urge the math averse to kindly recruit a math friend to help get this smiley.
Fibonacci Series
The Fibonacci series, named after Italian mathematician named Leonardo Pisano Bogollo, later known as Fibonacci, is a series (sum) formed by Fibonacci numbers denoted as Fn. The fibonacci series numbers are given as: 0, 1, 1, 2, 3, 5, 8, 13, 21, 38, . . . In a Fibonacci series, every term is the sum of the preceding two terms, starting from 0 and 1 as the first and second terms. In some old references, the term '0' might be omitted. The series has captured the interest of mathematicians and it continues to be studied and explored for its captivating properties.
Part 1 - Add up some positive Fibonnaci sequences
Add up the Fibonacci series from:
F(n) 9 to 14 = A
F(n) 22 to 25 = B
F(n) 29 to 30 = C
Fibonacci Series Sub-total = A + B + C
Part 2 - Cut down series by applying some trigonometry
Take your Fibonacci Series Sub-total * SIN(30) = D
D = Solution
Poke your solution "D" in to the checker
