ALL astronomical telescopes show upside down images. It is completely normal.

For terrestrial viewing you can buy an erecting diagonal to flip the image over. Like this one:

A new telescope has a rubber piece on the end with screws cant see through is it supposed to be removed ?

That is the end with the MIRROR! Turn it around-- the focuser is on the UP end of the telescope and the PICTURE that Fixya uses (above) is ALSO mounted upside down! The scope above is pointed at the ground!

Many beginners mount the scope backwards.

Why is everything upside down and backwards, With my vivitar telescope

All astronomical telescope show upside down images. It's normal, nothing is wrong with your scope. You can buy an "erecting prism" diagonal for terrestrial viewing.

Everything is upside down on side eye piece. When viewing through the scope that's on the side of the telescope itself, everything is upside down. No matter which way it is turned, the same problem exists.

All astronomical telescopes show upside down images. It's completely normal. Nothing is wrong with the scope. For terrestril viewing you can buy an "erecting prism diagonal" which will turn the images right side up.

Viewfinder views things backwards

Yes, most finder scopes show upside down images, it's completely normal.

This is an astronomical telescope. Even the main tube shows upside down images unless you use what is called an "erecting prism" for terrestrial viewing.

The end with the FOCUSER is the UP end. The mirror is the BOTTOM.

Like the picture in your question. The small finder scope is also mounted near the focuser as in the picture above.

You probably have the scope tube mounted upside down !

Just came into a used tasco 302048 . Everything is upside down!!!

the scope is made for both terrestrial viewing and astronomical. In order to see terrestrially upright, you need an inverting STAR DIAGONAL. The eyepiece will do nothing for inverting the image. you might have 2 diagonals in the kit that came wih the scope. the diagonal is the part that fits into the scope. then you place the eyepiece in the diagonal. if you have 2 diagonals , one is a 90 degree angle,(astronomical) and one is a 45 degree angle, (terrestrial). the eyepieces change the magnification of the image. the bigger the number (9mm, 20mm, 26mm,) the smaller the image. the smaller the number , the bigger the image gets. the number is inverse of the image. Hope this helps.

I can't see out ofscope

An inverted image is what you should see. Astronomical telescopes show an upside down image in the eyepiece. If you want to use your scope terrestrially you can add an erecting prism at the eyepiece.

Seeing land upside down

This is not only perfectly normal, but for this type of telescope, imperative! Land (and everything else) seems upside down due to how the light is bounced between the mirrors. It can be kinde tricky to get used to, but it's the way all Newtonian reflectors (it's the type of scope you have, big mirror at the botom, smaller one that's at a 45 degree angle neer the top, and an eypece on the side of the tube) are.
