Recently, a Symbolab developer contacted me about some new features of the service. First, Symbolab is now more than just a search tool. It includes a free graphing calculator and a free integrals calculator. Symbolab has also added a neat chemical reactions calculator. Finally, students can now find practice problems on Symbolab. The practice problems cover a wide array of topics in math. Most topics cover in the practice problems are accompanied by helpful videos for students to review if they get stuck on a problem.

**Applications for Education**

There are other sites and apps that provide similar services to those of Symbolab. Not being a math teacher myself, I can't say that Symbolab is inherently better than its competitors. I will point out that it's nice to have multiple options for students to choose from when looking for free scientific calculators.
