When simplifying half reactions what does it mean to cancel out species?

So when you have one species as a reactant in the first half-reaction and you have the same species as a product in the second half-reaction, you can cross out/cancel both when you add both reactions to make your overall reaction.

In addition, besides canceling out species when they are present on both sides of a reaction, you can also cancel electrons if there are the same number of electrons on both sides.

If you have an equal amount of some molecule on both sides, you can cancel them out, because they don't change through the reaction.
