+In engineering, solving a problem begins long before we start coding or
+building models. Like any other engineering challenge, computational
+problems must first be clearly framed and understood. In this section,

+approach engineering problems, \textbf{translate real-world situations
+into structured programming logic}, and \textbf{use computational tools
+to implement, test, and refine solutions}.
