Scientific Calculator delivers exactly what its name promises, full scientific calculator with trig, logs, factorial, memory, history & full keyboard support, fast and free. Because it belongs to ToolsMonk's student tools collection, the whole workflow happens on a single page instead of being spread across separate apps or websites.
Typical jobs it handles include working through algebra, trigonometry, and calculus homework, evaluating multi-step expressions without retyping intermediate results, and physics and chemistry calculations that mix functions, powers, and constants. The same page works on desktop, tablet, and mobile, so it is equally quick for a single urgent task and for work you repeat every week.
Everything about Scientific Calculator is tuned for speed to first result, with privacy-friendly processing and the rest of ToolsMonk's tools nearby when the next task comes up.

Type or click an expression, the calculator parses the whole thing, respecting order of operations
The result previews live below your expression; press = or Enter to commit it to the history tape
Switch between DEG and RAD for trigonometry, and use memory keys to store running values
Full expression engine, type whole expressions like 2·sin(45)+√9, not just one operation at a time
Trigonometry (sin, cos, tan and inverses), hyperbolic functions, ln, log₁₀, log₂, exponentials and roots
DEG/RAD switch, constants π and e, factorials, powers, and parentheses with implicit multiplication
Memory keys (M+, M−, MR, MC), an Ans key, and a running history tape you can click to reuse
Full keyboard support and a live result preview as you type
Runs entirely in your browser, nothing to install, no signup
Working through algebra, trigonometry, and calculus homework
Evaluating multi-step expressions without retyping intermediate results
Physics and chemistry calculations that mix functions, powers, and constants
Quick checks during exam-style practice or lab work
Scientific Calculator exists to make one job effortless: full scientific calculator with trig, logs, factorial, memory, history & full keyboard support. Professionals, students, and one-time visitors all get the same instant, accurate results in the browser: no installation, no account, no waiting.
Privacy and portability drive the design: all processing runs locally in your browser, so your files and data never leave your device. It behaves identically in every modern browser, from a desktop workstation to a phone.
This Scientific Calculator evaluates whole mathematical expressions rather than single key presses, so you can type something like 2·sin(45) + √9 and get the right answer in one go. Under the hood it tokenises your input and evaluates it with correct operator precedence and associativity, the same rules your maths teacher uses.
It covers the functions students actually need: trigonometry and its inverses, hyperbolic functions, natural and base-10 and base-2 logarithms, exponentials, powers and roots, factorials, and the constants π and e. A DEG/RAD switch keeps trigonometry unambiguous, and implicit multiplication means 2π and 3(4) work as you'd expect.
Practical touches make longer work faster: memory keys accumulate running values, an Ans key reuses your last result, and a history tape records every calculation so you can click back to any earlier answer. Full keyboard support means you rarely need the mouse.
Everything runs locally in your browser, so it's instant and private. Pair it with the other ToolsMonk student tools, the Logarithm Calculator, Permutation & Combination, and GPA Calculator, for a complete maths workflow.
Use parentheses generously, they make intent explicit and avoid order-of-operations surprises
Switch to RAD before doing calculus-style trig, and back to DEG for geometry problems
Click a previous answer in the history tape to reuse it instead of retyping long numbers
