We'll create buttons for the numbers and operations, as well as a display area to show the input and result. We can use HTML for the structure, CSS for styling, and JavaScript for functionality.\n\n### Step 1: Create the Calculator Interface\n\nWe'll begin by updating your `index.html` to add the calculator structure.\n\n```html\n\n\n\n \n \n Pre-Algebra Calculator\n \n \n \n \n\n\n

\n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n

\n \n\n\n```\n\n### Step 2: Style the Calculator\n\nNow, let's add some basic styling to make the calculator look nice. Update your `style.css`:\n\n```css\nbody { \n margin: 0; \n display: flex;\n justify-content: center;\n align-items: center;\n height: 100vh;\n background-color: #f0f0f0;\n}\n\n#calculator {\n width: 300px;\n background-color: white;\n border-radius: 10px;\n box-shadow: 0 0 10px rgba(0,0,0,0.1);\n}\n\n#display {\n height: 50px;\n background-color: #222;\n color: white;\n font-size: 24px;\n display: flex;\n align-items: center;\n justify-content: flex-end;\n padding: 0 10px;\n box-sizing: border-box;\n}\n\n#buttons {\n display: grid;\n grid-template-columns: repeat(4, 1fr);\n}\n\n.btn {\n padding: 20px;\n font-size: 18px;\n border: 1px solid #ddd;\n cursor: pointer;\n background-color: #f9f9f9;\n transition: background-color 0.2s;\n}\n\n.btn:hover {\n background-color: #eee;\n}\n```\n\n### Step 3: Implement Calculator Logic\n\nNext, we'll add the functionality to your `script.js` to handle button clicks and perform calculations.\n\n```javascript\n// script.js\n\nlet displayValue = '';\nlet firstOperand = null;\nlet secondOperand = null;\nlet currentOperation = null;\n\nfunction setup() {\n noCanvas(); // No need for p5.js canvas\n let buttons = selectAll('.btn');\n buttons.forEach(button => {\n button.mousePressed(() => handleButtonClick(button.html()));\n });\n}\n\nfunction handleButtonClick(value) {\n if (!isNaN(value) || value === '.') { // If it's a number or decimal\n displayValue += value;\n } else if (value === 'C') { // Clear\n displayValue = '';\n firstOperand = null;\n secondOperand = null;\n currentOperation = null;\n } else if (value === '=') { // Calculate result\n if (firstOperand !== null && currentOperation !== null) {\n secondOperand = parseFloat(displayValue);\n calculate();\n currentOperation = null;\n }\n } else { // It's an operation (+, -, *, /)\n if (firstOperand === null) {\n firstOperand = parseFloat(displayValue);\n } else if (currentOperation !== null) {\n secondOperand = parseFloat(displayValue);\n calculate();\n }\n currentOperation = value;\n displayValue = '';\n }\n select('#display').html(displayValue || firstOperand);\n}\n\nfunction calculate() {\n switch (currentOperation) {\n case '+':\n firstOperand += secondOperand;\n break;\n case '-':\n firstOperand -= secondOperand;\n break;\n case '*':\n firstOperand *= secondOperand;\n break;\n case '/':\n firstOperand /= secondOperand;\n break;\n }\n displayValue = firstOperand.toString();\n}\n```\n\n### Explanation:\n- **HTML File:** Defines the structure with buttons for numbers and operations.\n- **CSS File:** Styles the calculator to look neat and centered.\n- **JavaScript File:** Manages the calculator logic, handling button presses and performing calculations.\n\nYou can now replace the code in your files with these updates.

You might add a simple note below the display.\n\n```html\n

Enter fractions as numerator/denominator (e.g., 1/2)
