What is a Scientific Calculator?
Our Scientific Calculator is a browser-based expression evaluator that goes beyond basic arithmetic. Type an expression using standard operators and it computes the result immediately, respecting the normal order of operations โ parentheses first, then exponents, then multiplication/division, then addition/subtraction. It's built for quick calculations while studying, checking a formula, or verifying arithmetic without opening a separate app.
How It Works
The calculator reads the text you type, keeps only safe mathematical characters, converts the caret symbol into JavaScript's exponent operator, and evaluates the expression:
* โ multiplication / โ division
^ โ converted internally to ** (exponent/power)
% โ modulus (remainder), not "percent of"
( ) โ grouping / order of operations
Worked Example
Expression: 2^10
2**10 = 2 ร 2 ร 2 ร 2 ร 2 ร 2 ร 2 ร 2 ร 2 ร 2 = 1024
A second example combining parentheses and multiplication: (15+9)*2 โ (15+9) = 24, then 24 ร 2 = 48. The parentheses force the addition to happen before the multiplication, exactly as in standard maths.
How to Use This Calculator
- Type your expression into the input box using +, โ, *, /, ^, and parentheses.
- Click Calculate.
- The evaluated result appears immediately below.
Things to Know
- Multiplication and division are always evaluated before addition and subtraction unless you use parentheses to force a different order.
- Negative numbers work as expected:
-5+3returns -2, and(-5)^2returns 25. - Very long or deeply nested expressions still resolve instantly since the whole calculation runs locally in your browser.
For equations rather than plain expressions, try our Quadratic Equation Solver, or explore the Logarithm Calculator for log-based work.
