About this project

What you'll build: Make a basic calculator app with a clear button-grid, similar to the one on your phone. You'll design a simple user interface and program the calculator to handle basic math operations like addition, subtraction, multiplication, and division.

Why it's a good starter: This project is perfect for beginners because it focuses on one main idea-making a calculator-and guides you step-by-step. You'll see visible results quickly, which is motivating, and you'll practice both designing and coding in a friendly environment.

What you'll learn: You'll get hands-on experience with building a graphical interface, handling button clicks, organizing code, and testing your app. These are useful skills for any future programming projects!

Milestones

1. Setup & Plan

10 marks 5d

Submit a short plan describing your calculator's features, a sketch of the button layout (on paper or digital), and set up your project folder. Done when plan is clear and code editor is ready.

2. Core Build: Interface

30 marks 10d

Submit your code with a working calculator window showing all buttons in a grid (digits, operations, clear, equals). Done when the interface displays correctly and buttons are clearly labeled.

3. Core Build: Functionality

35 marks 10d

Submit updated code where buttons perform their actions-users can enter numbers, choose operations, and see results. Done when calculator handles +, -, ×, ÷, and clear functions correctly.

4. Testing & Polish

15 marks 7d

Test your app for bugs, fix any errors, and improve the look (e.g., spacing, button size). Submit before/after screenshots and describe what you tested and improved. Done when calculator is reliable and looks neat.

5. Demo & Short Report

10 marks 7d

Record a 1-minute screen demo showing your calculator in use, and write a short summary (100-200 words) on what you built and what you learned. Done when both are submitted and clearly show your work.
