Most-Used Math Calculators

The Percentage Calculator is the single most-searched math tool - used for discounts, exam marks, profit/loss, and percentage change. The Ratio Calculator handles proportions in three modes: simplify, find missing value, or scale to a total. For data sets, the Mean Median Mode Calculator returns a full descriptive summary in one step.

For higher-level work, the Quadratic Equation Solver returns real and complex roots, discriminant, and vertex - and the Logarithm Calculator handles log₁₀, ln, and any arbitrary base using the change-of-base formula. The Standard Deviation Calculator correctly distinguishes population (÷N) from sample (÷N−1) standard deviation.

Data analysts - Mean/Median/Mode, Standard Deviation
Scientists and engineers - Logarithm, Exponents, Scientific Calculator
Business professionals - Percentage change, Ratios, Averages

Frequently Asked Questions

What types of percentage calculations can I do?

The Percentage Calculator handles three modes: what is X% of Y, X is what percent of Y, and percentage change from X to Y. All three modes are in a single interface.

Does the quadratic solver handle complex roots?

Yes. When the discriminant (b² − 4ac) is negative, the Quadratic Equation Solver returns complex conjugate roots in the form a ± bi, along with the discriminant value and vertex coordinates.

How does the standard deviation calculator work?

Enter a comma-separated list of numbers into the Standard Deviation Calculator. It returns both population SD (σ, divide by N) and sample SD (s, divide by N−1), along with mean, variance, and dataset count.

Can I use the scientific calculator for trigonometry?

Yes. The Scientific Calculator includes sin, cos, tan, and their inverses in both degree and radian modes. For dedicated triangle solving, see the Trigonometry section.
