Solve the equation for the perfect mad scientist costume

The Mad Scientist character has its roots in 19th-century literature, with iconic figures like Dr. Frankenstein from Mary Shelley's Frankenstein leading the charge. The image of the eccentric, boundary-pushing scientist really took off in early 20th-century films and comics, where these characters often combined brilliance with a touch of insanity. 

They were known for their wild hair, maniacal laughter, and questionable experiments. As a Halloween costume, the Mad Scientist is a perfect blend of creativity and chaos, giving wearers the freedom to embrace their inner genius (or madness!) while having fun.
