The difference between the actual and experimental value is always the absolute value of the difference. |Experimental-Actual|/Actualx100 so it doesn't matter how you subtract. The error comes from the measurement inaccuracy or the approximation used instead of the real data, for example use 3.14 instead of π. navigate here

You look up the density of a block aluminum at room temperature and find it to be 2.70 g/cm3. What is your percent error?Solution: experimental value = 8.78 g/cm3 accepted value = 8.96 g/cm3Step 1: Subtract the accepted value from the experimental value.8.96 g/cm3 - 8.78 g/cm3 = -0.18 g/cm3Step 2: Take The result of the difference is positive and therefore the percent error is positive. his comment is here You measure the dimensions of the block and its displacement in a container of a known volume of water.
