Trump: No praise for passing a cognitive test Donald Trump has expressed frustration that he doesn't get credit for completing a complex arithmetic challenge three times. He detailed the task: "Take any number, say 49, multiply by 3, divide by 4, add 2019, subtract 87, divide by 3, multiply by 9. He noted that most participants fail at stage five, with few surviving to stage thirty. "I did it. I did it three times no one talks about it," he claimed. Trump also posted photos of himself completing the test.
