## Key Differences

Sum primarily deals with the basic arithmetic operation of adding numbers to get a single result. In contrast, summation extends to more complex mathematical contexts, such as adding a sequence of terms calculated from a formula.

Sum is commonly used in everyday math, involving straightforward addition of values. On the other hand, summation is frequently seen in statistical and algebraic equations, involving a set of rules or functions.

While sum can be computed manually or with a simple calculator, summation might require specialized mathematical tools or software, especially when dealing with large sequences or formulas.

Sum is typically taught at elementary levels of education due to its simplicity, whereas summation is introduced in higher mathematics, reflecting its complexity and range of application.

Sum often appears in simple financial calculations, such as totaling bills or expenses, while summation is integral in fields like engineering, physics, and advanced economics for dealing with series and complex calculations.
