Scientific calculator
Type a whole expression with brackets, powers, roots, logs and trigonometry.
Quick answer
The scientific calculator reads a whole expression with brackets, powers, roots, logs and trigonometry, in the usual order of operations. Formula: Brackets first, then powers (^) and factorials (!), then × ÷ and mod, then + −. For example, (2 + 3) × 4 = 20, and sin(30) = 0.5 in degrees.

Order of operations: brackets, powers, then multiply and divide, then add and subtract.
How is a scientific sum calculated?
Type or paste the whole expression and the answer updates as you type. Spaces do not matter, and × ÷ − are accepted as well as * / -.
Multiplication can be left out next to a bracket, a function or pi: 2pi and 3(4 + 5) both work.
Pick degrees or radians for the angle functions. In degrees, exact angles such as sin(180) give exactly 0.
Nothing you type is sent anywhere: the expression is read by a small parser in your browser, never run as code.
What is the formula for a scientific sum?
- Brackets first, then powers (^) and factorials (!), then × ÷ and mod, then + −
- sin, cos and tan take degrees or radians, as chosen; log is base 10 and ln is the natural logarithm
- pi = 3.14159265… and e = 2.71828182…
Can you show a worked example of a scientific sum?
(2 + 3) × 4 + sqrt(16) = 5 × 4 + 4 = 24. In degrees, sin(30) = 0.5, and 5! = 5 × 4 × 3 × 2 × 1 = 120.
What are the values of common functions?
Worked out in degrees where an angle is involved.
| Expression | Value |
|---|---|
| sin(30) | 0.5 |
| cos(60) | 0.5 |
| tan(45) | 1 |
| sqrt(2) | 1.41421356237 |
| cbrt(27) | 3 |
| log(1000) | 3 |
| ln(e) | 1 |
| 5! | 120 |
| 2^10 | 1,024 |
| pi | 3.14159265359 |
Common questions
How do I enter a power or a root?
Use ^ for powers, so 2^10 = 1,024. For roots use sqrt(x) or cbrt(x), or raise to a fraction: 27^(1/3) = 3.
Is it degrees or radians?
Your choice. Degrees is the default; switch to radians with the list under the expression.
What is the difference between log and ln?
log is the base-10 logarithm (log(1000) = 3) and ln is the natural logarithm, base e (ln(e) = 1).
How do I find a factorial?
Put ! after a whole number: 5! = 120. Factorials up to 170! are supported.
Does it follow the order of operations?
Yes: brackets, then powers, then multiplication and division, then addition and subtraction. So 2 + 3 × 4 = 14.
