alleryFor Q = A + B with absolute errors a and b: error in Q:
Aa - b
Ba/b
Ca × b
Da + b (in subtraction or addition, absolute errors add)
Answer & Solution
Correct answer: D. a + b (in subtraction or addition, absolute errors add)
For Q = A ± B: ΔQ = ΔA + ΔB.
ABSOLUTE errors add (worst case).
**In product/quotient:** RELATIVE errors add.
