Amazing Addition, Subtraction, Multiplication, or Division application designed to help kids who struggle organizing and lining up numbers. This app is completely customizable and users can choose any of the operations, the number of problems to practice, the number of digits in each number of the problem (multiplying a three-digit number by a two-digit number for example), and the amount of numbers in each problem (adding 3 numbers for example). Users can draw straight lines on the screen simply by touching and dragging and can choose (for division) whether or not the problems should have remainders. The program gives immediate feedback and allows users the opportunity to correct answers that are incorrect. Mini numbers are provided for regrouping.
