A Karnaugh Map simplifies complex boolean calculations. It is a visual tool used in digital electronics and logic design to minimize boolean expressions without the need for extensive algebraic manipulation. By organizing truth values in a grid format, Karnaugh Maps allow designers to easily identify and eliminate redundant terms in boolean equations. This is particularly useful when dealing with expressions involving multiple variables, as it helps to highlight common factors and enables simpler implementations in hardware design, such as reducing the number of logic gates required for a given function.

In contrast, the other options do not align with the primary purpose of a Karnaugh Map. It does not deal with arithmetic operations, graphical representations, or data structures in a direct manner. Instead, its sole focus is on providing a straightforward method for simplifying boolean functions, making it an essential tool in the realm of digital systems design.
