Matt Parker introduces a number trick in a Numberphile video. The trick involves picking a one-digit number, repeating it to form a three-digit number, summing the digits, and dividing the three-digit number by the sum. The result is always 37. Parker demonstrates this with the number 6 and explains the mathematical reasoning behind it, showing that the trick works for any one-digit number due to the properties of multiplication and division.
