Rubik's Cube - Orienting the Last Layer Corners

I am Bob Burton, Rubik's Cube Expert, and I am teaching you how to solve a Rubik's Cube. At this point we now have the first two layers solved and the last layer edges oriented. The next step is to orient the corners of the Rubik's cube. To do this, we want to look for a solved corner, a corner where the yellow stickers are already facing up. We also want the other three positions to not be yellow stickers. If we have this, we put the yellow sticker with the correct corner in the front left position. Then using the right and top layers of the Rubik's cube, we move the right layer up, the top layer to the left, the right layer down, the top layer to the left again, the right layer up, the top layer twice, and the right layer down. This completely solves the yellow face. Sometimes we get other positions where we don't have any yellow stickers, or it might have two yellow stickers. If we have this we want to look for a way that we can do the same move that we just did, and end up with one correct yellow sticker. This is always possible. Looking in this case, it helps to know what the algorithm we just did does. It keeps the correct corner the same, and it rotates the other three corners of the Rubik's cube clockwise. So, whatever sticker is on top would move clockwise to the side, and any sticker that would move clockwise to be up to the top will move to the top. If we look at this particular case, if we have this one correct, we look at what happened to the other three. This one move up, which means that will have a yellow sticker to the top here. This one, when we move this corner clockwise, this yellow sticker stays to the side. This yellow sticker moves to the top, that means that we will have yellow stickers in the two corners here. This is no good because we only want one yellow sticker. If we move the top clockwise, we check again. This corner will stay the same. This corner, the yellow sticker will move to just back here, when we move the piece clockwise. This one move to the top and this one will stay to the side. That means we will end up with one correct yellow sticker. So, we will do the algorithm; right side up, top to the left, right side down, top to the left, right side up, top side twice, right side down. Now, we have the yellow correct sticker already in the front left. We could do the algorithm we know; up, left, down, left, up, top twice, down. Sometimes we may need to do this twice, but that's okay, as long as we remember what to do in that case, always be able to solve the yellow face of the Rubik's cube. Now that we have the yellow face solved, we move on to solving the edges of the Rubik's cube puzzle completely.
