What can the expression tab evaluate?

Standard arithmetic with parentheses, powers and modulus, trigonometric and inverse trig functions, hyperbolic functions, logarithms (ln and log10), roots, rounding functions and the constants pi, e and phi. Degrees or radians, your choice. Ans recalls the previous result.

Does it solve equations?

Yes: quadratic equations with the discriminant shown (including complex roots), and pairs of simultaneous linear equations via Cramer’s rule.

Which number bases are supported?

Binary (2), octal (8), decimal (10) and hexadecimal (16), converted in every direction at once.

Is my input sent anywhere?

No. The parser runs entirely in your browser and only accepts mathematical expressions - it cannot execute code.

Five Calculators Behind One Clean Interface

The All-in-One Advanced Calculator replaces a drawer full of single-purpose tools. Switch tabs to move from a live scientific expression evaluator to percentage questions, equation solvers, base conversion and number theory - each one instant, each one showing its working.

What Each Tab Does

Expression - evaluates as you type, with a function keypad, Ans memory and degree/radian switching.
Percentage - answers the three classic questions (X% of Y, % change, part-of-whole) in one view.
Equations - quadratic roots with discriminant, plus 2×2 simultaneous equations.
Number Bases - decimal, binary, octal and hexadecimal in all directions.
Number Theory - GCD, LCM, modulo, primality and prime factorization.
