Mixing PCM Audio Samples

I have a simple question regarding mixing multiple PCM samples.

I read that the best way to mix multiple PCM audio samples is to take the average number of samples in each frame.

So, if I add together, say 5 16-bit samples, before dividing by 5, it is obvious that it will have more value than can be enough for 16 bits.

So, when mixing multiple 16-bit samples, do I save them all in int first and add them and average and then convert them back to short?

If you want to mix audio samples, you simply add them together. Building an average is not the right way to do this.
