Trump Defends Unusual Math Claims on Drug Prices, War Timeline

President Donald Trump has embraced what critics are calling “fake math” to describe his administration’s achievements, particularly regarding prescription drug prices, during a White House event announcing a deal with drugmaker Regeneron.

During Thursday’s Oval Office gathering, Trump defended his past claims that his policies had reduced prescription medication prices by “500%, 600%” — figures that mathematicians point out are mathematically impossible, as prices cannot be reduced by more than 100% without manufacturers paying consumers to take their products.

When confronted with this mathematical reality, Trump acknowledged using these inflated percentages but suggested there were “two ways of calculating” such reductions. “We also sometimes say 50%, 60%,” Trump stated, calling it a “different kind of calculation” that could reach “70, 80 and 90%.”

“People understand that better,” Trump added. “But they’re two ways of calculating, and either way, it doesn’t make any difference.”

Health and Human Services Secretary Robert F. Kennedy Jr. attempted to explain Trump’s percentage claims during the event. Kennedy had faced questioning on this same issue the previous day during a Senate Committee on Finance hearing, where Senator Elizabeth Warren (D-Mass.) challenged the administration’s mathematical claims.

Kennedy suggested that Trump’s calculations referred to reversing previous price increases implemented by pharmaceutical companies. “If the drug was $100, and it raised the price to $600, that would be a 600% rise,” Kennedy said — though this calculation itself is incorrect, as a $500 increase on a $100 base is actually a 500% rise.

“And the president used that mathematical device,” Kennedy continued, though experts note that no such legitimate mathematical principle exists for the way Trump characterized these reductions.

Mathematical experts point out that while prices can increase by more than 100% (a product rising from $1 to $2.10 represents a 110% increase), they cannot be reduced by more than 100% without dropping to zero and then into negative territory — effectively meaning consumers would be paid to use the product.

The drug pricing comments weren’t Trump’s only questionable mathematical claims during the event. When asked about the ongoing conflict with Iran exceeding his original four-to-six-week timeline, Trump insisted he had actually met his own prediction because Iran’s military was “decimated” within that period, despite the fact that the war, which began on February 28, continues more than seven weeks later.

While the U.S. and Iran recently agreed to a ceasefire that Trump announced he was extending, neither side has declared the conflict over. Military operations may be paused, but a formal conclusion has not been reached within the timeframe Trump originally predicted.

The president also revisited another longstanding numerical dispute during the event — the size of his 2017 inauguration crowd. While discussing renovations at the Lincoln Memorial Reflecting Pool, Trump compared his inaugural attendance to Martin Luther King Jr.’s historic 1963 “I Have a Dream” speech.

“I had the same exact crowd. Maybe a little bit more,” Trump claimed, adding that photographic evidence supported his assertion. “I actually had more people. But that’s OK.”

This renewed claim recalls the controversy that emerged during Trump’s first days in office, when then-adviser Kellyanne Conway famously defended disputed inauguration attendance figures by referring to “alternative facts” — a phrase that has since become emblematic of the debate over factual accuracy in political discourse.

The drugmaker Regeneron, whose deal with the administration was the ostensible focus of Thursday’s event, has not publicly commented on the president’s mathematical assertions regarding pharmaceutical pricing.
