Bug fixing
The program will be useful for students of primary schools and their parents.
There is a lot of math puzzles:
1. Order of numbers
2. Addition
3. Subtraction
4. Finding unknown number (eg 3 + ... = 6)
5. Numbers comparison
6. Multiplication
7. Division
All the tasks are split into levels from simple to hard.
I created this program for my child but I hope that it will be useful for other children and their parents.
