Mixing operations
2^5 = 32, and adding a square root on top: 2^5 + sqrt(16) = 36.

How it works
The expression is read left to right but resolved by precedence: parentheses first, then functions and exponents, then multiplication and division, then addition and subtraction — the same order taught in school (often remembered as PEMDAS). A leading minus sign binds more loosely than exponentiation, so −2^2 evaluates to −4, matching the convention used by most programming languages and calculators.
Functions are written with parentheses around their argument, like sin(30) or sqrt(16) — the degrees/radians toggle affects only sin, cos, tan and their inverses; sqrt, log and the others behave the same either way.

Assumptions and limits
- All calculations happen in the browser using double-precision floating point, the same precision virtually all calculators use.
- Only the listed functions and constants are recognized — custom variables are not supported.
Frequently asked questions
What order of operations does this follow?
Parentheses, then exponents, then multiplication/division/modulo (left to right), then addition/subtraction (left to right) — the standard convention used in math and in virtually every programming language.
How do I enter a negative exponent, like 2 to the power of −3?
Write 2^-3 — the parser reads the minus sign as applying to the exponent.
Does log mean base 10 or natural log?
log is base 10 here, matching how most calculators label it — use ln specifically for the natural (base e) logarithm.
Why did I get an error?
Usually an unmatched parenthesis, an unsupported function name, or dividing by zero — double-check the expression for typos and balanced parentheses.
