Explanation#1(quick-and-dirty, and at least makes sense for curvature): As you probably know, the curvature of a circle of radius r is 1/r. In other words, if you expand a circle by a factor of k, then its curvature shrinks by a factor of k. This is consistent with the units of curvature ...Example 2.4.2: Addition and Subtraction with Significant Figures Rule: When we add or subtract numbers, we should round the result to the same number of decimal places as the number with the least number of decimal places (i.e., the least precise value in terms of addition and subtraction).
