Question

If x = a + b, the maximum absolute error in x when errors in a and b are Δa and Δb respectively is:
  1. A
    Δa − Δb
  2. B
    Δa × Δb
  3. C
    Δa + Δb
    Correct
  4. D
    |Δa − Δb|

Correct answer

Δa + Δb

Explanation

For addition or subtraction, absolute errors add up: Δx = Δa + Δb (maximum error). This ensures we account for worst-case combination of errors.
