Xmas Math
During the holidays, most of us like to goof off. And who would think of doing math on New Year's Eve? After all, these things are incompatible. Many people think so, but the authors of this game claim the opposite. Christmas math can very well be fun and exciting! Such that both adults and children will be happy to do it right at the New Year's table. Your task is to solve as many examples as possible in one minute. Moreover, you will not be looking for an answer, but a sign that will need to be placed between two numbers. Ready to test yourself? Then go ahead! Good luck in science and good winter holidays.
