This page gathers Figuro's math tools, from everyday arithmetic like percentages and fractions to algebra, geometry, and statistics. Each calculator is built to show its work: the formula it applies, a worked example, and the reasoning a textbook or teacher would walk through, not just a final number.
Evaluate expressions with trig, logs, and roots.
Simplify any fraction to its lowest terms.
Three common ways to calculate percentages.
Sale price and savings from an original price and discount.
Generate random whole numbers within a range.
Angles and area of a triangle from its three sides.
Mean, variance and standard deviation of a data set.
Volume of a cylinder, sphere, cube, cone, or rectangular box.
Area, circumference, and diameter of a circle.
Least common multiple and greatest common factor of two or more numbers.
Simplify ratios, solve for a missing value, and scale a ratio.
Slope, distance between two points, and midpoint.
Convert between binary, decimal, hexadecimal, and octal.
Solve ax²+bx+c=0 for real or complex roots.
Mean, median, mode, and range of a list of numbers.
Roll 1-10 virtual dice with any number of sides.
Convert between numbers and Roman numerals.
Find the hypotenuse or a missing leg of a right triangle.
All factors and the prime factorization of a number.
Solve equations and expressions step by step.
For everyday number problems — splitting a bill, figuring a discount, or comparing quantities — the Percentage, Percent Off, Ratio, and Fraction calculators cover most day-to-day arithmetic without needing algebra.
For algebra homework or problem-solving, the Quadratic Formula Calculator and Math Solver handle equation-based problems, while Factor and LCM & GCF cover the number-theory basics that usually come before algebra in a typical course.
For geometry — area, volume, angles, or side lengths — use Circle, Volume, Triangle, or the Pythagorean Theorem Calculator depending on the shape and the piece of information you're solving for.
For statistics, Average & Median and Standard Deviation both summarize a data set, but they answer different questions: averages describe the center of your data, while standard deviation describes how spread out it is.
Do these calculators show the steps, or just the final answer?
Each calculator page explains the formula it uses and walks through at least one worked example with real numbers, so you can follow the same steps with your own values rather than just reading off a result.
What's the difference between the Percentage Calculator and the Percent Off Calculator?
The Percentage Calculator handles general percentage math — what percent one number is of another, or what a percentage of a number equals. The Percent Off Calculator is built specifically for discounts, taking a price and a discount percentage to show the sale price and savings.
When should I use LCM & GCF instead of the Fraction Calculator?
Use the Fraction Calculator when you want to simplify, add, subtract, multiply, or divide fractions directly. Use LCM & GCF when you need the underlying building blocks — like finding a common denominator by hand, or simplifying a ratio to its lowest terms.
Can the Math Solver handle any equation?
It's built for common algebraic equation types students encounter in school, including linear and quadratic equations. For highly specialized or symbolic math (like calculus derivatives), a dedicated computer algebra tool would go further.
Why do I need both Average & Median and Standard Deviation for a data set?
They answer different questions. Average and median describe where the center of your data sits; standard deviation describes how tightly or loosely the data is clustered around that center. Two data sets can have the same average but very different spreads.
