I get this show via ROKU, it's, to say the least, unique. The host ... forget his name ... has a unusual laugh that is somewhat annoying to my ears. The questions are varied, but they have this one math problem which is incredibly difficult.
It's a kind of quiz show; the video in the OP is banter from one of the contestant teams. I get the impression the teams are made up of well known, in the UK, celebrities or public personna of some kind. Suffice to say I've never heard of most of them.
There are word quizzes and other kinds. For the math problem, they put some numbers up on a board, maybe four or five, and then a total, and the contestant teams have to derive a formula that uses the numbers to arrive at the total. Time limited, of course.
The numbers will be single or double digits ... say 3, 4, 8, and 11, and the number is typically high hundreds, like 756. Don't bother trying to solve my example, it's just made up values to illustrate a typical problem.
