Really sharp edges in Blender

I'm trying to make a car in blender, but the edges are really sharp. What's the way to fix this?

 

Click on smooth shading.

 

Where is that?

 

I thinks it in the tools tab.

 

Left side toolbar, there should be a thing called shading, underneath having 2 buttons called smooth and flat.

 

Thanks, now the edges are smooth.

But the shading's a bit weird. Is that fixable?

 

Go into edit mode, mesh, normals flip normals.

 

Or select it all (A), then press Ctrl+N.

 

Ok, I feel stupid for asking this, but I opened the save menu and I can't exit out of it. I tried restarting Blender, but that didn't work.

 

Top left there's a button that says back to previous.
