i'm not able to explain this as well as a physics major:

these are called "tartini beats"/"combination tones" etc: https://en.wikipedia.org/wiki/Combination_tone

They are actually always occurring (if the notes as sufficiently dissonant) - so the calculations are nothing more than subtraction ie. 440 - 215 = 5hz

some combination tones are louder than others usually as there is less phase cancellations occurring.

440 - 215 = 5?

I think you got the principle right but used the wrong A for your example (you used A4, probably meant to use A3)?

440 and 215 would interact as 440 and 430 (an octave above the 215) so you'd get a difference of 10 Hz, not 5. (And the sums as well, of course.)
