We invite you to our Christmas school. The board is decorated with Christmas tree garlands, an example is already written on it in chalk. To the left and to the right of the board, there are four Christmas tree decorations - multi-colored balls. Each of them has a mathematical sign: plus, minus, division and multiplication. You must choose a toy with a symbol and insert into the example to make it correct. If you chose what you want, you will see a bold green check mark right in the middle of the board. Try to solve the maximum number of examples in the Xmas Math game in the allotted time of sixty seconds. Add, divide, multiply, and subtract. The timer in the upper left corner is also on the board.
