Needing help with math homework one day got me thinking, so I decided to create my Calculator project with a Micro:bit to make adding and multiplying easier. I wanted to type in numbers and pick an operation to see the answer right away. It’s been fun learning how to use the Micro:bit to do math for me!

I started my code with a Micro:bit import and set it up to ask me for two numbers and an operation—like “+” or “*”—using input prompts. For example, I enter a first number like 5, then pick “+,” and a second number like 3. My code uses if-elif statements to check the operation: if it’s “+,” it adds them to get 8; if it’s “/” and the second number isn’t 0, it divides; but if I try dividing by zero, it says “Error (Division by Zero).” For anything else, it shows “Invalid Operation.” Then it prints the whole thing, like “The result of: 5 + 3 = 8,” so I can see it all.

I’m excited to make this calculator even better next time! Maybe I can add a button to start it instead of typing, or make the Micro:bit’s LEDs light up with the answer. I could also try adding more operations like squares. I’m happy I’m learning how to code math with my Micro:bit, and I can’t wait to show my friends how it helps with our homework!
