In the audio world, a "mixer" is a voltage adder. It has no real affect other than to combine
two or more signals into one signal path.
In the world of radio, a "mixer" is a voltage multiplier, which has the effect you describe.
In a synthesizer, we have the 4 quadrant multiplier
(balanced modulator, or ring modulator), whose output is the sum and difference of the
frequencies fed into it. They are very similar to the "mixer" used in fm radio.
The effect is often used to get bell or gong like sounds.

I am still getting my flippers wet with the diy thing.I have a
question.
If I calculate frequencies and vary the resistors of the inputs will
I be able to mix (add and subtract)different frequencies of the
inputs?I don't know what kind of effect this will have but I figure
it could be interesting.
Or is this a stupid idea.
Thanks for bearing with a newbie
Phil
