President Donald Trump, speaking at the White House, held up a chart showing proposed import taxes: 34 percent on China, 20 percent on the EU, among others.

The math behind Donald Trump’s sweeping and allegedly “reciprocal” tariffs may actually be simpler than it seems.With the help of a large chart, the president unveiled his latest wave of tariffs Wednesday on what he called “Liberation Day.

Economist Wojtek Kopczuk asked ChatGPT to calculate tariffs to balance out the U.S. trade deficit. He received a similar answer to the White House’s documentation, showing the AI used “a basic approach” that divided the trade deficit by the total trade. Entrepreneur Amy Hoy ran a similar experiment, yielding identical results from AI models.
