Scientific Calculator
A full scientific calculator with trig, logs, powers and roots — type or click.
Tips: multiplication can be implied — 2π, 3(4+1) and 2sin(30) all work. Powers group right to left, so 2^3^2 = 2^9 = 512. log is base 10, ln is the natural log, and % divides by 100. Click any line in the history to reuse it. Calculations use standard double-precision floating point, so results are rounded to 12 significant digits.
About the Scientific Calculator
The Scientific Calculator handles trigonometry in degrees or radians (including inverse functions), logarithms, powers, roots, factorials, percentages, constants such as π and e, and brackets — and it understands implied multiplication like 2π. Type with your keyboard or click the buttons, and reuse results from the history.
How to use the Scientific Calculator
- Choose degrees or radians for trigonometry.
- Type an expression or use the buttons — the answer previews as you type.
- Press Enter or = to calculate.
- Click any line in the history to reuse it, or use Ans for the last answer.
Frequently asked questions
Should I use degrees or radians?
Use degrees for most school geometry and everyday angles, and radians for calculus, physics and programming.
What is the difference between log and ln?
log is the base-10 logarithm and ln is the natural logarithm, base e (about 2.718).
What order does the calculator follow?
Standard order of operations: brackets, then powers (right to left), then multiplication and division, then addition and subtraction.
