Audio Math Question

I have a question: Assme I used my computer to make a 20Hz audio track and
a 20kHz audio track (both having the same amplitude), I burn it to CD, and
play it on my stereo.

How does the sound waves add together so you hear the 20Hz and the 20kHz at
the exact same time (assuming I have seperate sub-woofer and a tweeter)?

If you took the average of 20 and 20,000, you'd get (rounding off) 10,000
and would get a combiation of the two numbers.

So how are both sounds reproduced at the same time?
