## Graphing Calculator by Mathlab

If you're looking for a graphing calculator app that works smoothly and seamlessly, you've found it! Graphing Calculator by Mathlab is a scientific graphing calculator integrated with algebra and is an indispensable mathematical tool for students in elementary school to those in college or graduate school, or just anyone who needs more than what a basic calculator offers. It is designed to replace bulky and costly handheld graphing calculators and works on virtually any Android phone or tablet.

Furthermore, Graphing Calculator by Mathlab displays calculations as it performs them on the high-quality display of the Android device, making it easier for the user to understand the calculations and see them clearly. This app has two great strengths. First, it acts as a fine scientific calculator, but, more than that, it displays the intermediate steps of the calculations as you type. It allows the students to both watch and learn how the calculations are made and how to find the final answer. Second, the graphing ability is absolutely stunning! Not only does the calculator beautifully display the graphs, but it automatically generates the x- and y- values and displays them as well.

## Mathlab Arithmetics

Elementary math operations, addition, subtraction, multiplication and division. Displays results in tabular form. Shows carries, borrows and crossouts.

For elementary school students and their parents. This is NOT a calculator. Check your kids homework.

NOTE:

Add 0s after decimal point to increase precision of division results

5 / 2 = 2 remainder 1

5.0 / 2 = 2.5
