Point4D point1 = new Point4D(10, 5, 1, 4);
Point4D point2 = new Point4D(15, 40, 60, 75);
Point4D pointResult = new Point4D();

pointResult = Point4D.Subtract(point1, point2);
// pointResult is equal to (-5, -35, -59, -71)

// Displaying Results
syntaxString = "pointResult = Point4D.Subtract(point1, point2);";
resultType = "Point4D";
operationString = "Subtracting a Vector3D from a Point4D";
