Scientific Calculator — Online & Keyboard-friendly
A full keyboard-driven scientific calculator. Click the keypad or type expressions directly. Supports +, −, ×, ÷, parentheses, exponents (^), trig functions (sin/cos/tan and inverses), logs (ln, log), square root, factorials (!), and constants (π, e). Press Enter or click = to evaluate.
Keyboard shortcuts
Type 0–9, +, −, *, /, (, ), ., ^ directly. Enter or = evaluates. Backspace deletes. Escape or "c" clears. The same expression engine also powers the topbar quick-math bar — type `1500*1.07^10` there for an instant result without opening this view.
Functions and constants
Trigonometry: sin, cos, tan and inverses (asin, acos, atan) — angles in radians; multiply by π/180 to convert from degrees. Logs: ln (natural), log (base 10). Powers: ^ for exponentiation, sqrt for square root, ! for factorial. Constants: π, e. Parentheses group expressions normally; the engine respects standard precedence (^ before × / before + −).
Why a scientific calc on a finance app?
Two reasons. First, as a fallback — sometimes you want to compute something not covered by the financial calculators (a percentage, a square root, a quick proportion). Second, the same expression engine powers the topbar quick-math input — so you can type `(1200 + 300) * 1.07 ^ 10` from anywhere on the site without opening the full scientific view.
Frequently asked questions
- Do the trig functions use degrees or radians?
- Radians. To use degrees, multiply by π/180 first — for example sin(30 × π/180) for the sine of 30 degrees.
- Can I type expressions instead of clicking?
- Yes — type directly, including parentheses and ^ for powers, and press Enter to evaluate. The same engine powers the quick-math bar in the top toolbar.
How we calculate it
Expressions are evaluated with standard operator precedence: parentheses first, then exponentiation, then multiplication and division, then addition and subtraction. Trigonometric functions take angles in radians, and the constants π and e are built in.
What it doesn't do
- Symbolic algebra (this evaluates, it doesn't simplify)
- Graphing functions (no plotting)
- Matrices, vectors, calculus
