Full scientific calculator with trig functions, logarithms, powers and calculation history.
A scientific calculator in your browser means you've always got one available โ no app to install, nothing to carry, no batteries to replace. This one handles the full range of operations you'd expect: trigonometry, logarithms, powers and roots, factorials, and more.
It follows standard mathematical order of operations (BODMAS/PEMDAS), so complex expressions evaluate correctly without needing to break them into multiple steps. Useful for students working through maths or physics problems, tradespeople doing on-the-fly calculations, and anyone who occasionally needs more than a basic four-function calculator.
Trig functions default to degrees rather than radians, which is what most people need most of the time. There's a mode toggle if you're working in radians.
BODMAS (Brackets, Orders, Division, Multiplication, Addition, Subtraction) is the standard order of mathematical operations. Yes โ this calculator evaluates expressions in the correct order, so 2 + 3 ร 4 gives 14, not 20.
Radians are used in higher-level maths and physics, particularly in calculus and when working with circular motion. Degrees are used in most everyday trigonometry, geometry, and navigation. If you're not sure which to use, you almost certainly want degrees.
log (or logโโ) is the logarithm base 10 โ the power to which 10 must be raised to equal a number. ln is the natural logarithm (base e โ 2.718). In most engineering and scientific contexts, ln is more common. In everyday calculations and decibel measurement, logโโ is typical.
EXP (or e^x) raises Euler's number e (โ2.71828) to the power you enter. It's the inverse of the natural logarithm and comes up constantly in finance (continuous compounding), physics, and statistics.
