Free Student Calculator
A full scientific calculator that runs right here in your browser. Homework, revision and exam practice, with no app to install and nothing to pay.
The same calculator widget that lives inside Study Mode.
What This Calculator Can Do
Beyond everyday arithmetic, percentages and brackets, you get the functions school actually asks for: sine, cosine and tangent with switchable degree and radian modes, natural and base-10 logarithms, powers, square roots, factorials, absolute values and remainders. Memory keys (M+, MR, MC) hold running totals across multi-step problems, and the inverse toggle doubles the function set without cluttering the keys.
Built For Homework
Three copy buttons sit above the keys. Copy Result grabs the answer as plain text for worksheets and chat. Copy Raw takes the unrounded value for further working. Copy LaTeX formats the whole expression so it pastes cleanly into documents and assignment editors that understand math notation. The display keeps your full expression visible while you type, so a misplaced bracket is easy to spot before you hit equals.
Three Quick Tips
Match your mode. Trigonometry answers go wrong most often because the calculator is in radians while the question uses degrees. Check the DEG/RAD indicator first. Chain with memory. Store an intermediate result with M+ instead of retyping long decimals. Estimate first. A rough mental answer tells you instantly if a typo slipped into a long expression.
