Simple CAS Calculator Write mathematical expressions neatly, calculate results, and solve equations directly with GeoGebra CAS. The tool supports both numerical and symbolic results, angle settings in degrees or radians, percentages, fractions, powers, trigonometric functions, and equations with variables. Results can be copied as plain text, as an equation, to Google Docs, or as an image, making it easy to use in assignments, teaching materials, and documents
Load one or more datasets and create a complete statistical overview with summary statistics, frequency tables, and charts. The tool checks the data step by step, helps identify the correct data type, and supports raw observations, frequency tables, grouped interval data, categorical data, and data copied directly from Excel. You can compare multiple datasets, adjust intervals manually, rename or delete datasets, copy tables and charts, export CSV files, save projects, and print or save the results as PDF. The tool is designed to help students understand both the calculations and the visual representations of data.
This tool helps students calculate triangles step by step. They can choose a right triangle or a general triangle, enter the known values, and the tool finds the missing sides, angles, perimeter, and area. It also shows a sketch, relevant formulas, and clear intermediate steps to support learning.
Understand volume as space inside a 3D object and surface area as the area covering it. Click a shape or use the dropdown to open a 3D model. The measurements written on the figure are the values used in both calculations.
A clear and student-friendly tool for working with percentages. Calculate percentages, parts, wholes, increases, decreases, discounts, and percentage changes. The calculator shows the answer, step-by-step calculations, and visual models to help students understand what the percentage means.
Convert between units quickly and clearly. Choose a category, enter a value, select the original unit, and the tool automatically shows the value converted into all available units in that category. The converter supports different unit types such as length, area, volume, mass, time, speed, temperature, and more. It is designed to give students a clear overview of how the same value can be written in different unit
Create a clear matrix from two sets of options. Enter your values line by line, choose whether order matters and whether repetition is allowed, and see all possible combinations in a structured table. The tool can also calculate sums, products, differences, ratios, powers, and dice/Meyer combinations when using numbers. The table can easily be copied into Word, Excel, or other documents.
Build and explore counting trees visually. Create combinations, test ordered and unordered outcomes, and export your results for teaching, learning, or further analysis.
Create clear probability trees with two or three steps. Enter outcomes and probabilities as fractions, percentages, decimals, or whole-number percentages, and the tool automatically calculates the combined probability for every path. The generator shows both a table and a visual probability tree. Branches can be color-coded, probabilities can be shown on each branch, and selected outcomes can be added together. Results can be exported to Word, Excel, or downloaded as an SVG image.
Here is our digital formula collection. We have tried to divide the formulas into different sections, making them easy to find.
Create mathematical simulations explore randomness, probability, and patterns.
Compendium on GeoGebra for the Classic version (Version 5). An introductory booklet with exercises to be solved using GeoGebra. Version 2, now with descriptions of some of the exercises. Version 3, now including box plots.
