2020 presidential candidate and entrepreneur Andrew Yang traded the traditional American flag lapel pin for another one that said "math" instead during the Democratic debates in Ohio.

Yang has been no stranger to breaking the mold when it comes to debate fashion. He wore the flag lapel pin on the right side of his jacket during the Houston debates, instead of the left.

Yang also goes tie-less during debates. During the debate in Florida, NBC anchor Brian Williams said, "Do you look at Mr. Yang and say, 'Would it kill you to throw on a tie?'"

Entrepreneur and 2020 presidential candidate Andrew Yang traded the traditional American flag lapel pin for another one that said "math" instead during the Democratic debates in Westerville, Ohio.

"Math" is an acronym for "Make America Think Harder," according to Yang, a play on President Donald Trump's slogan of "Make America Great Again," or MAGA. Yang has also anchored his campaign on his Asian American identity, often referencing "math" in political punchlines and town halls — for example, "I'm the opposite of Trump, an Asian man who likes math."
