JUX-639 ### Step 1: Understanding the Task The first step was to comprehend what the task entailed. I needed to design a calculator that could perform addition, subtraction, multiplication, and division. Additionally, the calculator should incorporate a graphical user interface (GUI) for easy interaction. This meant that I’d need to write a program that could handle these operations and display a math console for users to interact with. ### Step 2: Designing the Calculator With the requirements in mind, I began designing the calculator. I decided that the calculator should have a GUI with different buttons for each operation and a display screen to show the input and results. ### Step 3: Setting Up the GUI I decided to use a popular programming language for building GUIs, such as **[?](https://www.example.com) Python. I chose **[?](https://www.example.com) tkinter because it’s widely used and well-documented. My first task was to create a basic window for the calculator. ``` from tkinter import * root = Tk() root.title("Calculator") root.main() ``` **Forward:** I started by checking a** Running: I focused on the basics of setting up a tkinter window. I was able to create a basic window with a title "Calculator". ### Step 4: Adding Inputs and Display Next, I wanted to add a display screen where the input and results would be displayed. I decided that the screen should have a size of 16 pixels wide to ensure visibility. ``` from tkinter import * root = Tk() root.title("Calculator") root.geometry("16x16") welcome = Label(root, text="Welcome to 1234 Calculator") welcome.pack() Creating a simple window was simple enough, but I needed to incorporate inputs and display features for the calculator. I decided that the calculator would have a functionality to perform these operations via a simple GUI. ### Step 5: Implementing Buttons I then began to add buttons for each operation - addition, subtraction, multiplication, and division. I needed to determine the layout of the buttons and how they would interact with the calculator. My first thought was to have the buttons placed horizontally across the screen, with each button representing a specific operation. ``` from tkinter import * root = Tk() root.title("Calculator") root.geometry("16x16") welcome = Label(root, text="Welcome to 1234 Calculator") welcome.pack() lbl = Label(root, text="Insert the number here") lbl.pack() btn = Button(root, text="Click here to press") btn.pack() ## inspecting Browser: I focused on analyzing the basic structure of the calculator. I was able to create a basic window with a title "Calculator" and add a label and button to it. ### Step 6: Building the Operation Functionality With the buttons established, I needed to implement the mathematical operations they would perform. I decided that each operation should be handled by a separate function that would take the numbers entered by the user and compute the result. ``` def add(input, answer): return input + answer def subtract(input, answer): return input - answer def multiply(input, answer): return input * answer def divide(input, answer): return input / answer ``` **Forward:** I was able to create functions that would perform the four basic mathematical operations on the calculator. I was now ready to incorporate these functions into the calculator. ### Step 7: Incorporating the Functions With the operation functions in place, I needed to link them to the buttons on the calculator. This meant that a user would press a button, and the calculator would perform the corresponding action. ``` from tkinter import * root = Tk() root.title("Calculator") root.geometry("16x16") welcome = Label(root, text="Welcome to 1234 Calculator") welcome.pack() lbl = Label(root, text="Insert the number here") lbl.pack() btn = Button(root, text="Click here to press") btn.pack() ``` ### Step 8: Finalizing the Calculator The last phase was to finalize the calculator by ensuring that all the necessary functions were in place and that the calculator was user-friendly. I made certain that the buttons were easy to access and that the calculations were accurate. #### Conclusion: Through these steps, I was able to design a simple calculator that could perform basic mathematical operations. This endeavor not only tested my skills in coding but also taught me valuable skills in problem-solving and software design.
