Scientific Calculator
Calculate fractions, roots, powers, logarithms, trigonometric functions, constants, and factorials with a clean online scientific calculator.
Online scientific calculator for readable math expressions
This scientific calculator handles common engineering, school, and everyday math expressions while keeping the input easy to read.
Use it for fractions, powers, roots, trigonometry, logarithms, constants, factorials, and quick repeated calculations with Ans.
Features
- 2D math input for textbook-style expressions.
- Keyboard-friendly scientific functions and template buttons.
- DEG/RAD mode for angle calculations.
- History and copy tools for repeated work.
- Friendly errors for undefined or incomplete expressions.
Example expressions
2^8\sqrt{144}\sin(45^\circ)\frac{3}{4}+\frac{5}{8}\ln(e^2)\frac{6!}{3!}
How to use this calculator
- Enter a numeric expression with the keyboard or the calculator buttons.
- Choose DEG or RAD before using trigonometric functions.
- Use history or Ans when you want to continue from the last result.
Common input mistakes
- Check angle mode before using sin, cos, tan, asin, acos, or atan.
- Use parentheses around a function argument if the expression has more than one term.
- This is a numeric calculator, so undefined variables such as x cannot be evaluated unless replaced with numbers.
FAQ
What makes this different from a normal calculator?
The input is displayed as structured 2D math, so fractions, roots, and powers are easier to check before calculating.
Can I use it for engineering homework?
Yes. It supports the common scientific functions needed for many school and engineering calculations.
Does it use JavaScript eval?
No. Expressions are converted and evaluated with a math parser instead of JavaScript eval.
Can it show a fraction result?
The main result is decimal, and a fraction approximation is shown when the value is suitable.
