๐ข Scientific Calculator
A scientific calculator handles what a basic one cannot: sine, cosine and tangent for angles, logarithms for growth and decay, powers and roots, and factorials for combinatorics. Type an expression or tap the keys โ everything runs instantly in your browser.
Angles for the trig functions are in degrees. Use parentheses to control the order of operations, just like on a handheld calculator.

How to use this calculator
Tap the on-screen keys to build an expression in the display, then press equals for the instant result. Everything runs in your browser, so there is nothing to install.
- Press the digit keys and the plus, minus, multiply and divide keys to type your expression in the display.
- Add scientific keys as needed: sin, cos and tan for angles, sqrt for square root, x squared for squaring, plus pi and e for constants.
- Use the parentheses keys to group parts of the expression so the order of operations stays the way you intend.
- Press the equals key to see the answer, and press clear (C) to start over with a new calculation.
Frequently asked questions
What can this scientific calculator compute?
It evaluates full expressions with basic arithmetic plus trigonometry (sin, cos, tan), logarithms, powers, roots, factorials, and the constants pi and e. Angles for the trig keys are measured in degrees.
How does it handle the order of operations?
It follows standard precedence: parentheses first, then exponents and roots, then multiplication and division, then addition and subtraction. Add parentheses whenever an expression could be read two ways.
Can you show a worked example?
Try the expression 3 squared plus the square root of 16 times 2. The keypad squares 3 to get 9 and takes the square root of 16 to get 4, then computes 9 + 4 * 2 = 17.
Why did my answer look wrong?
A leftover operator or an unmatched parenthesis from the previous entry is the most common cause, so tap clear before starting a new problem. Also double-check that any angle you entered is in degrees, not radians.
