Completely Free Mathematical Graphing Tools

I recommend a mathematical tool website called Desmos, which provides a variety of math-related tools including function graphing, polynomial equation solving, data visualization, and more—completely free for students, teachers, and math enthusiasts.

Desmos was founded in 2011 and has been operated by a nonprofit organization ever since. Its mission is to help everyone learn and fall in love with mathematics, growing alongside it. We firmly believe that everyone is a potential mathematician; some just haven’t had the necessary opportunities, encouragement, or tools to discover their math talent. With these tools, users can express their ideas mathematically, flexibly connect different representations, make conjectures, and develop entirely new ways of thinking.

Desmos is accessible within China and offers a Chinese-language version. It boasts a vast user base with nearly 100 million monthly visits, and over 75 million people worldwide use Desmos annually.

Desmos supports more than 20 languages and receives high praise from its users. By allowing students to visualize functions in real time, it significantly boosts their enthusiasm for learning and helps them better understand mathematical concepts.

In some countries, Desmos is even integrated as an official mathematical tool in exams, mainly for middle school and university-level math tests, providing students with essential assistance during assessments.

Desmos primarily offers six types of mathematical tools, with the three graphing tools—especially function graphing—being the most widely used.
