A scientific calculator removes the ceiling from your mental math: trigonometry, logarithms and powers that a basic calculator can't touch, all available in your browser with no installation.
Beyond the four operations
The four basic operations handle everyday sums, but science, engineering and finance need more: powers and roots for growth, logarithms for scale, and trig for angles. This calculator puts them all on one keypad.
Order of operations
The expression engine respects standard precedence — brackets first, then powers, then multiplication/division, then addition/subtraction. That means you can type a whole expression and get the mathematically correct answer, not a button-by-button approximation.
Local and private
Because every keystroke is evaluated in your browser, nothing you compute leaves your device — handy for sensitive figures you'd rather not paste into a web form.
Frequently asked questions
Everything a basic calculator does plus trigonometry (sin, cos, tan and inverses), logarithms, exponents, roots, factorials and constants like π and e.
Press the function button (it types something like sin( ), enter the number, then close the parenthesis with the ) button and press =.
Yes — every calculation happens locally in your browser. Nothing is sent to a server.
