Introduction

A feature-rich smart calculator built using Python's Tkinter library. This calculator not only performs basic arithmetic operations but also handles advanced mathematical functions and supports voice commands.

Features

• Basic arithmetic operations: addition, subtraction, multiplication, and division.
• Advanced mathematical functions: square root, power, factorial, trigonometric functions, logarithmic functions, and more.
• Speech recognition for voice commands.
• Graphical User Interface (GUI) with easy-to-use buttons and input field.
• Error handling for invalid inputs.

Installation

Prerequisites

Make sure you have the following software installed:

• Python 3.x
• tkinter library (comes pre-installed with Python)
