## Game instructions for addition

Addition belong to the four basic arithmetic operations and the correct mathematical way of talking about it is:*adding two numbers*.

Two terms add up to the sum:

4 | + | 7 | = | 11 |

term | + | term | = | sum |

### Calculation of knowledge points

Each completed level results in 1 knowledge point. The maximum number of points (35 knowledge points) is achieved when you complete all 35 levels. You'll get a bronze medal when you complete a level 2 times and a silver medal after 5 completed rounds. A gold medal will be received after 10 completed rounds. In Addition, the maximum number of collectable gold medals is 35. You only earn knowledge points for levels that has not been cleared before. A cleared level has a green background above. Even when you have completed a level, you can continue practicing at that level, but it gives you no more knowledge points.### Similar games
