Build Your Own Arcade Calculator: Multiplication, Addition, Subtraction

We'll create an arcade-style calculator interface using HTML and CSS.First, we'll add a display screen at the top of our calculator.Our HTML structure uses semantic elements for the calculator layout.Next, we'll create a grid of number buttons using CSS Grid layout.Our CSS styles give the calculator its arcade feel with retro fonts and button effects.We'll add operation buttons for addition, subtraction, and multiplication.Each button provides visual feedback when pressed, creating an engaging user experience.The calculator layout is responsive, adapting to different screen sizes.Media queries ensure our calculator works well on all devices.With our structure complete, we're ready to add the calculator's core functions.When a number button is clicked, an event listener captures the input and updates the display.The event listener function handles all number button clicks, updating the display value while preventing leading zeros.Each arithmetic operation is handled by a separate function that ensures proper number conversion using parseFloat.When an operation button is clicked, we store the first number and operator, then reset the display for the second number.The calculate function determines which operation to perform and handles the computation.Input validation prevents multiple decimal points and ensures proper number formatting.The entire process flows from input validation through calculation and formatting.To make our calculator more engaging, we'll add arcade-style features starting with the interface.Each button press will trigger both visual and sound feedback.When a calculation is correct, the score increases and particles burst from the display.If an error occurs, we'll show an arcade-style error message and reset the streak.A high score system tracks your best calculation streaks.All these elements work together to create an engaging, arcade-style calculator experience.
