How to make Mathematica save a notebook with "input 1" and "output 1" on the left of cells? If I open a saved notebook, those tags are gone.

You need to change the value of the option CellLabelAutoDelete to False. This can be done at the Cell, Notebook, or Global level. This can be done using Format > Option Insepctor... or SetOptions.

For one Notebook:

SetOptions[EvaluationNotebook[], CellLabelAutoDelete -> False]

Globally (overridden by Notebook options):

SetOptions[$FrontEnd, CellLabelAutoDelete -> False]
