Jimmy Fallon proved Wednesday that President Donald Trump’s gutting of the Department of Education doesn’t add up. (Watch the video below.)

The department this week announced the dismissal of at least 1,300 employees, reducing its workforce by about half since Trump’s second term began.

“Trump just announced he’s firing 50% of the Department of Education,” the “Tonight Show” host said. “Even worse, Trump said, ’Don’t worry, the other 60 percent will still have jobs.’”

Arithmetic wasn’t the president’s only problem in the comedian’s monologue. Trump’s new alphabet song imagined by Fallon might not catch on with youngsters.

“ABCD, ELON, ME. TARIFFS, JK, T-R-U-M-P,” it begins.

Check out the rest of the song below in Fallon’s lesson on Trump’s education moves, beginning at 1:24:
