Solidity Tutorial: Build a Calculator Smart Contract | Functions, Math Operations

Learn Solidity by building a simple yet powerful Calculator Smart Contract on Ethereum! 💻✨ In this tutorial, we’ll cover: ✅ Writing functions for addition, subtraction, multiplication, and division ✅ Using require statements for input validation ✅ Understanding int256 vs uint256 ✅ Fetching results with view functions (gas saving tips) ✅ Testing your contract step-by-step in Remix IDE By the end of this video, you’ll not only have a working calculator but also a strong foundation in Solidity basics that apply to real-world dApps like DeFi, games, and governance systems. 📌 Code Repository 👉 GitHub Repo: https://github.com/codebyankita/solid... (File: Calculator.sol) 🛠️ Tools Used Remix IDE (for deployment & testing) Solidity ^0.8.13 JavaScript VM environment 🧑‍💻 Try It Yourself Open Remix IDE Create a new file: Calculator.sol Paste the code from the repo Compile and deploy the contract Test all the functions (add, sub, mul, div, getResult) 🌍 Connect with Me 🔗 GitHub: [CodeByAnkita](https://github.com/codebyankita) 📝 Medium: [@ankitacode11](  / ankitacode11  ) 💼 LinkedIn: [Ankita Virani](  / ankita-virani-4bb478282  )
