Eight-year-old math whiz Parker Garrison realized that a new exhibit at Discovery Place didn't quite add up:
When the 8-year-old math whiz at Charlotte Christian visited the "Jelly Belly Presents Candy Unwrapped" display, he accepted the challenge: Use equations to calculate how many jelly beans were in a pyramid and other containers.
His mother, Donna, didn't want to wait while he tried all the formulas. So she copied the numbers he needed, and he took the problems home. That's when he realized something was wrong. ...
The equation mistakenly called for dividing the correct answer in half. Parker's father, Jim, called Discovery Place. After the museum figured out who should handle the call, Dean Briere, a shocked vice president, decided to investigate.
An hour later, Briere called back. The exhibit had traveled to eight cities in four years. "And no one found this mistake -- I just couldn't believe it," Briere said.
