Calculate A – B.
A – B ≈ -1.860981941 or A – B ≈ -1.861
NOTE: If you used the rounded values to compute the new problem, you would get
A – B ≈ -1.86.... which is incorrect!
Calculate C + D.
C + D ≈ 1.194880677 or C + D ≈ 1.195
NOTE: If you used the rounded values to compute the new problem, you would get
C + D ≈ 1.194.... which is incorrect!
