Column Addition Game

The game "Column Addition" is an online assistant for learning the mathematical action of adding numbers in columns. In this game you can test your knowledge by adding three, four and five digit numbers. The game is suitable for students in grades 2-3-4. The game has only 3 levels, which differ in the length of the numbers for addition. Remember that adding numbers always goes from right to left. If as a result of adding several digits we get the sum equal or greater than 10, the one is added to the next digit, and in place of the question mark is placed digit, which remained. For example, if we add 9 and 4, we get 13. We add 1 to the next digit and put 3 instead of the question mark.
