## Calcgame: have fun with math!

Calcgame is a puzzle with numbers. And it is a great tool for children to have fun (and competition) with math!

You get 4 different digits. With one or more of these digits and possibly one or more of the other calculator buttons you must make the value "1". When you succeed, you go to the next level and must create the value "2" , and so on. The goal is to reach the highest possible level with the given digits. When you are stuck, you can start a new game with different digits.

For example: with the digits 1, 3, 5, 7 you can reach level 79 with solutions like

1 = 1 Just a digit

11 = 1+3+7 Digits and +, -, X or /

17 = 17 2 digits combined to a number

64 = (7+1)x(3+5)

79 = 71+3+5
