                      Write an algorithm to calculate the average of three numbers.

                                                                                               Mathematics

                            SYSTEM MAP TO SHOW RELATIONSHIPS

                     A system map is a visual tool that shows how different parts of a system are connected and affect
                     each other. It helps you understand cause-and-effect relationships and how changes in one part
                     can affect the whole system.

                     A system  map  is created  using the Loopy  website:  https://ncase.me/loopy/v1.1/.
                     This website allows designing interactive maps where elements (nodes) influence each
                     other through positive or negative feedback loops.

                     KEY COMPONENTS OF A SYSTEM MAP

                     To understand how a system works, we need to explore its key components and how they are
                     connected.
                         Elements: Parts or variables in the system (e.g., CPU speed, software efficiency).

                         Relationships: How elements affect each other.
                        Positive (+): One element increases another (e.g., faster CPU Æ better software performance).

                        Negative (–): One element decreases another (e.g., more programs Æ less memory).
                         Feedback Loops: Outputs loop back as inputs.
                         Reinforcing Loop: Amplifies effects (e.g., more users Æ more data Æ better hardware).
                         Balancing  Loop: Stabilises  the system  (e.g., high CPU temperature  Æ cooling  system  Æ
                        temperature lowers).

                     SOLVING PROBLEMS USING SYSTEM MAPS

                     Example: System Map for Online Account Safety

                     Problem: Weak passwords, reused logins and ignoring 2FA (two-factor authentication) lead to
                     many hacked accounts. Build a system map to understand and improve account safety.
                     Key elements: Password Strength, Use of Two-Factor Authentication (2FA), Number of Accounts.
