Issue with Zoom Functions

I just installed blender onto my laptop and everything for the most part is going fine, however for some reason I can not zoom in or out with the - or + symbols. I plugged in a normal keyboard and this worked the only problem is that it seems to change the view windows on its own and even when I switch back it just switches back again.

Any ideas on what the problem is? Also, how do you move the screen from side to side, it’s great to zoom in and out but what about moving the screen from left to right.

I really want to learn this program, but this is taking the fun out of it.

I’ll re post this in the support section. Sorry
