MATH & ALGEBRA TOOLS

Math & algebra tools

Free online math calculators for graphing functions, solving algebra, finding polynomial roots, analysing data, and working with matrices.

TOOL COLLECTION

Choose a focused tool for the task.

Graph functions, solve equations, find roots, calculate statistics, and work with matrices.

Plot and compare several functions, inspect value tables, trace x-values, and adjust the graph window directly in your browser.

Choose a one-variable polynomial workflow or build a coefficient system with 2–8 variables and a transparent matrix-solving method.

Enter coefficients for a polynomial of degree 1 to 10 and calculate real or complex roots numerically.

Build or paste flexible matrices, then calculate arithmetic, row reduction, inverse, rank, cofactors, adjugate, 2×2 eigenvalues, and A·x = b systems.

Analyse raw data, frequency pairs, or X/Y pairs using descriptive statistics, quartiles, standard deviation, and linear regression.
