General Electric CEO Jeff Immelt has all the qualifications you would expect of a Fortune 500 chief executive.
The Cincinnati-born son of a GE employee studied at Dartmouth and earned a Harvard MBA before working his way up at the industrial giant he now helms.
But Immelt says his most invaluable qualification is not the MBA. It is his undergraduate degree in math.
"I use my math major every day — I don't use the MBA quite as much," Immelt said, speaking at Business Insider's IGNITION 2015 conference on Wednesday.
"My intellectual curiosity goes more toward problem solving than spreadsheets."
Of course, Immelt said, he understands the mechanics of running a business and all the other things you learn in business school.
But running a company, to him, is really about problem solving. And that's something he learned about in his undergraduate studies, due to "the inherent intellectual curiosity around math and physics."
That has stayed with Immelt throughout his career.
"I'm just curious about everything," he said. "I can view every situation as a problem to be solved, and I've never lost my passion for that as I've grown in my career."
