🧮

Basic Calculator

Everyday calculations, made simple.

🌸

Multiply the brackets to expand them.

Enter the four coefficients for (ax + b)(cx + d). Use 1 for x, or 0 if a term is missing.

First x coefficient (a) First constant (b) Second x coefficient (c) Second constant (d)

Your expanded expression will appear here.

Example: (x + 2)(x + 3) expands to x² + 5x + 6.

🧩

Write a quadratic expression as a product of brackets.

Enter the coefficients for Ax² + Bx + C. This tool finds factorisations with integer coefficients.

x² coefficient (A) x coefficient (B) Constant (C)

Your factorised expression will appear here.

Example: x² + 5x + 6 = (x + 2)(x + 3).

⭐

Find the lowest common multiple or highest common factor.

Enter two whole numbers (0 or greater), then choose the calculation you need.
