What functions does this scientific calculator include?

It includes trigonometric functions (sin, cos, tan), logarithms (log base 10 and natural log ln), powers and exponents, square roots, and the constants pi and e, alongside standard arithmetic.

Does it handle order of operations correctly?

Yes. It respects standard mathematical precedence and parentheses, so expressions like 2+3*4 or (5+2)^2 evaluate correctly.

Is it free and private?

Yes. It runs entirely in your browser with no signup, and nothing you type is sent to a server.

Does log mean base 10 or natural log?

On this calculator log is base 10 and ln is the natural logarithm (base e), the common science and engineering convention.

Can I use it on my phone?

Yes. The button layout works on any device — phone, tablet, or computer.

Scientific Calculator — Advanced Math in Your Browser

This free scientific calculator handles far more than basic arithmetic. It supports trigonometric functions, logarithms, powers, roots, and the constants pi and e, all with correct order of operations and parentheses — everything you need for science, engineering, and higher-level math. It runs instantly in your browser with no app, no signup, and complete privacy, since nothing you calculate leaves your device.

The Functions You Need

Beyond add, subtract, multiply, and divide, it includes trigonometry (sin, cos, tan), logarithms (log base 10 and natural log ln), powers through the x^y button, square roots, and the constants pi and e. Parentheses let you group operations so complex expressions evaluate exactly as intended.

Correct Order of Operations

A good calculator must respect precedence, and this one does: multiplication and division before addition and subtraction, powers before those, and parentheses overriding everything. So 2 + 3 × 4 correctly gives 14, and (5 + 2)² gives 49 — the results proper math expects, without splitting the calculation into pieces.

Who It Is For

Students working through algebra, trigonometry, physics, or chemistry get every function they need. Engineers, developers, and anyone doing quick technical math get a capable tool without opening a heavy application, on any device.

Free, Private, and Instant

No cost, no account, no limits. Everything runs locally in your browser, so your work stays private and it even functions offline once loaded. Explore our other calculators for percentages, ratios, and statistics, all built to the same free, private standard.
