Where has the minus signed come from? I'm confused!

I changed the ratio moved to drag up instead of down, since in android drag down
means refresh page, and disabling that will complicate the code. So made it drag
up.

+    expected_y = math.floor(div_height * -0.25)
+
+    self.assertEquals(div_position_x, expected_x,
+                    msg="Moved element's left coordinate: %d, expected: %d" %
+                    (div_position_x, expected_x))
+    self.assertEquals(div_position_y, expected_y,
+                    msg="Moved element's top coordinate: %d, expected: %d" %
+                    (div_position_y, expected_y))
