Decimals with Herra Kaali play online

"Decimals with Herra Kaali" is a fun app, to help kids learning decimals operations, by practicing unlimited exercises.

Herra Kaali (in Finnish means "Mister Cabage") is a cartoon character who loves to teach kids various things. In this context, he will try to teach the kids about decimals, by providing unlimited exercises for them to practice.

Right now, the App has two operations, additions and subtractions.
For each operation, a set of 10 exercises is provided every time the section is accessed.
Under each exercise, there is an input field ("answer here") where the user will enter the answer.
When all the answers are filled in, the user can check the results, by using the button "Check results" (note that all the exercises should have an answer).
For each exercise, when checking the results, it will show an OK/NotOK icon next to the input field and will color the answer with green or red, based on the answer's correctness.
If the answer is wrong, the correct answer will be displayed under that particular exercise.
After checking the results, the user can start a new exercise for the same operation, or can navigate to the homepage, in order to select a different operation to practice.

Have fun and good luck learning decimals!
