Unique in its approach, the **Lehmann Algebra Series** uses curve fitting to model compelling, authentic situations, while answering the perennial question “But what is this good for?” **Lehmann** begins with interesting data sets, and then uses the data to find models and derive equations that fit the scenario. This interactive approach to the data helps readers connect concepts and motivates them to learn. The curve-fitting approach encourages readers to understand functions graphically, numerically, and symbolically. Because of the multi-faceted understanding that they gain, readers are able to verbally describe the concepts related to functions.
