Everything a scientific calculator does
Use the on-screen keys or type directly: expressions like 2sin(30)+√(16) or 5!/(2^3) are evaluated with correct order of operations, and a live preview shows the answer as you type. Switch between degrees and radians, use 2nd for inverse trig functions, and recall the previous answer with Ans.
The last 20 calculations are kept in the history panel — click any to use it again. Results are cleaned of floating-point noise, so 0.1 + 0.2 shows 0.3.
How to use the scientific calculator
- 1
Enter an expression
With the keys or your keyboard.
- 2
Choose DEG or RAD
For trigonometric functions.
- 3
Press = or Enter
The result replaces the expression.
- 4
Reuse results
With Ans or from the history.
Key features

sin, cos, tan and inverses in degrees or radians.
Logs and powers
log, ln, xʸ, 10ˣ, eˣ, √ and x².
Factorial and constants

Common uses
- Students: Maths, physics and chemistry problems.
- Engineers: Quick checks without opening an app.
- Everyday: Complex percentages and powers.
Tips and good to know
- Multiplication can be implied: 2π and 3(4+1) work without a × sign.
- Powers are evaluated right to left: 2^3^2 = 2^9 = 512.
- For working with fractions exactly, use the Fraction Calculator.
Frequently asked questions
How do I switch between degrees and radians?
Press the DEG/RAD key. The current mode is shown under the display.
How do I calculate inverse sine (sin⁻¹)?
Press 2nd, then sin. In degree mode, sin⁻¹(1) = 90.
Does it follow BODMAS / PEMDAS?
Yes. Brackets, powers, multiplication/division and then addition/subtraction are applied in the correct order.
