Python is a popular programming language for its simplicity and vast functionalities. One of its great features is the ability to handle and code math equations. Whether for academic, scientific, or data analytic needs, coding equations in Python can be a swift, seamless process. In this tutorial, you will learn how to code basic and complex equations in Python.

### Step 1: Basic Mathematical Operations

In Python, you can perform basic mathematical operations such as addition (+), subtraction (-), multiplication (*), division (/), and exponentiation (**). Below is an example of using these operations:

1 2 |
result = 15 + 3 * (2 - 1) print(result) |

The output should be:

18

### Step 2: Complex Equations

For more complex equations, Python provides the power of libraries such as NumPy and SymPy. NumPy allows you to handle high-level mathematical functions, linear algebra, Fourier transformation, and more. SymPy adds symbolic computation capabilities to Python.

To handle complex equations like quadratic equations (ax² + bx + c = 0), we can use the NumPy’s roots function.

1 2 3 4 5 |
import numpy as np coeff = [1, -2, 1] # a=1, b=-2, c=1 for x² - 2x + 1 = 0 roots = np.roots(coeff) print(roots) |

This code will output:

[1. 1.]

### Step 3: Using SymPy for Symbolic Computations

SymPy comes in handy when you want to handle symbolic computations. It can solve equations, perform calculus, manipulate expressions, and more! Here’s an example where a symbolic equation is solved.

1 2 3 4 5 6 |
from sympy import symbols, Eq, solve x = symbols('x') eq1 = Eq(2*x + 1, 1) sol = solve(eq1, x) print(sol) |

This code will output:

[0]
