Is there an easy way to calculate the distance to which a lens will focus after adding a 10 or 16mm extension tube or both? (I know I will lose infinity focus, whatever the h€|l that means)

Hint. It must be really easy because I’m really stupid. No point in offering any complicated equations because I will just lose the will to live.

See if this page is of any use:

Thanks for the contribution. According the the calculation my minimum focus distance increases to 78.4 from 70cm…
