Hi

With the spread of the Cavid 19 virus and the closure of schools with this program, you can make up for your children's academic retardation in math.

Working on the program is such that you first select one of the mathematical operations (addition or subtraction) and then select the level (easy, medium and hard) and the program gives you numbers relative to the selected level. And answer the questions from you. If done correctly, it will give you a point. Displays all correct and correct answers.
