How to cut clips from middle of a video

For the love of God and Jesus, someone please explain to me how to cut clips from middle of a video, so that i can remove the unwanted clip ? I searched in youtube, all they show is how to trim, trim and trim clips. Even if I use Blade and cut the unwanted section and delete it, how do I reconnect back the remaining clips ? All they show is that you can only reconnect the clips that you have cut with Blade, and not after deleting in-between clips. When I cut the unwanted section by selecting and using the "cut" option, only the video is cut and audio is left behind. Again after that comes the question of how to rejoin the clip after cut. So complicated and I'm so frustrated. So please someone guide me. Even though I'm a beginner in final cut pro, I searched a lot but could not find the solution. Never had I had such problems with any other software for such a simple task.
