NUMEQ Scientific Calculator

NUMEQ is a scientific calculator for math study, practice, and everyday calculations. Start without an account and perform calculations on your device, including offline.

Enter fractions, roots, and powers in natural mathematical form. Move the cursor to edit expressions, choose DEG or RAD for angle calculations, and view an exact form when available alongside a decimal approximation.

Use arithmetic, trigonometric and inverse trigonometric functions, logarithms, factorials, π, e, and the previous answer Ans. Menus also provide equation, inequality, matrix, statistics, complex-number, function-table, and numerical-integration tools.

AC clears the display while retaining Ans. SHIFT with the back key can return to the previous calculation. Choose a key sound or mute it.

Numerical root searches do not guarantee every solution. A search that finds no root does not by itself prove that no root exists.

For iPhone and iPad with iOS or iPadOS 26.0 or later. Calculator menus and in-app help are provided in Simplified Chinese. Use of phones or calculator apps in examinations depends on the examination rules.

Support and privacy pages are currently available in Simplified Chinese.
