Hello Is there a right order to stack lenses that magnify? For example if I have lens with 6x magnification and a lens with 2x magnification which order would I stack them to get 8x magnification. Do I put the 2x lens on top of the 6x lens or 6x lens on top of the 2x lens or it doesn't matter? Thank you

Hello I was wondering if I put a box on the ground and then walk 100 yards away, the distance between the box and me is 100 yards. At 100 yards if I clime a tree will the distance between me and the box decrease as elevation increases? If yes then by how much will it decrease if I am elevated 50 yards from the ground? Thank you
