Why is it ok to write additional zeros to the right of a decimal without affecting its value?
Because they are simply for 'padding' - Take for example the following numbers... 12.3, 10.02, 11.004... in order to make them easier to add up, you would 'pad' the shorter numbers with zero's to make them all the same length. Thus 12.3 becomes 12.300 and 10.02 becomes 10.020. It's easier to add... 10.020 11.004 12.300 Than to add... 10.02 11.004 12.3 Note, however, that adding extra zeros to the right of the decimal point implies greater precision in the number so, when you express the final result, your should do error analysis and write the correct number of digits based on the individual accuracies.
