Significant digits or figures are not something we make up to terrorize you all semester long. They represent the accuracy of a measurement. For example, a cheap bathroom scale bought at the dollar store reads your weight as 152 pounds, not 152.45809 pounds. It is not that accurate. Significant digits are very important in all measurements.
