```
private void multiplicationExample()
{
Matrix matrix1 = new Matrix(5, 10, 15, 20, 25, 30);
Matrix matrix2 = new Matrix(2, 4, 6, 8, 10, 12);
// matrixResult is equal to (70,100,150,220,240,352)
Matrix matrixResult = Matrix.Multiply(matrix1, matrix2);
// matrixResult2 is also
// equal to (70,100,150,220,240,352)
Matrix matrixResult2 = matrix1 * matrix2;
}
```
