If the measured values of two quantities...

If the measured values of two quantities are `A +- Delta A` and `B +- Delta B`, and `Delta A` and `Delta B` being the mean absolute errors. What is the maximum possible error in `A + B`? Show that if `Z=frac(A)(B)` then `frac (Delta Z)(Z)`=`frac (Delta A)(A)`+`frac (Delta B)(B)`
