Mathematics for IGCSE & O level - Limits Of Accuracy (Section 1 - No. 49)
What is the correct way to calculate the upper bound of a difference, when calculating with two values, A and B, each given to a unit of accuracy?
U(A) - L(B)
U(A) - U(B)
L(A) - L(B)
L(A) - U(B)
Explanation
The upper bound of a difference is found by subtracting the lower bound of the value being subtracted from the upper bound of the value being subtracted from.
