A small company ‘flow computing’ specializes in writing small programs that can be given away to students to help them with their learning.

They want your help to create a program that will help students with their maths. You will be one of many computing students who will be creating a program so they want you to come up with your own design without being too limited by design constraints. You are therefore to design your own program. It MUST include a Graphical User Interface (GUI). It can be aimed at ANY age.

These solutions may offer step-by-step problem-solving explanations or good writing examples that include modern styles of formatting and construction of bibliographies out of text citations and references. Students may use these solutions for personal skill-building and practice. Unethical use is strictly forbidden.
