I have created a very useful tool for every person goes to school yet.I am 15 and i am going to school and when i am bored to do it with the pencil my program has helped me a lot.
Whoever want to see my program or wanna take it,
he ought to just to send me a mail in my pm(or to tell it here) to give it.
(It isnt difficult to be created as program but it is really useful as doing with it your exercises for school).
