How accurate is the following calculation? 2008-09-03 From Craig:Given that these numbers are only accurate to 2 decimal places, how accurate is the following calculation? 1.73 - 2.16 + 0.08 + 1.00 - 2.23 - 0.97 + 3.02 = 0.47 How do I work out the accuracy?Answered by Penny Nom.     Calculations 2002-12-15 From Mahdi:This problem is rather general, but it usually makes a lot of problems. I almost have no difficulty in math and physics questions, but unfortunately I'm not at all accurate in simple one or two digit calculation. I even sometimes make silly mistakes in simple sums like 7+4=12 or 4+5=11! Is there any effective way to reduce these mistakes? Answered by Walter Whiteley.
