## What is Graphing Calculator + Math PRO?

The Graphing Calculator + Math PRO app **provides a full scientific graphing calculator for mobile devices, easy to use on the go and just as powerful as its clunky predecessors**.

The **Android-only** Graphing Calculator + Math PRO app is rated for **users of all ages** and can be **downloaded for $8.99 in the Google Play store**. Graphing Calculator + Math PRO does not contain any in-app advertisements or additional purchases.

The Graphing Calculator app is an excellent tool for students, and therefore excellent to be used in tandem with tradition TI graphing calculators, as it displays calculations as it performs them, helping users to watch and learn the process for finding the final answer to a problem.

While school rules and Texas Instruments' complete monopoly in the educational market may mean that students are unable to use the Graphing Calculator app for test-taking.

The Graphing Calculator + Math PRO app is capable of the following functions:

**Scientific Calculator
**

- Square root, cube and higher roots (hold √ key)

## Is Graphing Calculator + Math PRO safe for my kids?

Parents will be pleased to learn that the Graphing Calculator + Math PRO app can safely replace the purchase of an expensive TI graphing calculator for students, at the low price of $8.99.

However, the only downside to the Graphing Calculator app is that it may pose an issue at test-taking time, as many school districts or teachers do not allow students to have smartphones or tablets out during exams.

Created by Mathlab apps, parents should know that the Graphing Calculator + Math PRO app is highly rated by users in the app store, with a 4.8 out of 5 rating. In short, the app comes highly recommended.

In all, parents have nothing to worry about with the Graphing Calculator + Math PRO app -- in fact, they just might find that their child has a better grasp on mathematics from using it! **This app is safe for kids**.
