Yes!!! I needed an app that had a step by step conversion and this is the only one with it! Would have rated 5 stars if it had a bin/hex/dec/oct calculator too. (But if you plan on implenenting that too, make sure to do it with step by step.)

Awesome! Awesome app with a lot of functions!

## Graphing Calculator MathlabPRO

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.

## Free Graphing Calculator

Free Graphing Calculator

Does far more than most of the paid calculators out there . . . let alone the free ones.

Features:

1) Scientific Calculator. Simple to grasp and easy to use, but powerful features are available when you need them. Available functions include the following:

• the usual arithmetic functions and exponentiation.

• square root, cube root, nth root, natural log, log base 10, log of arbitrary base, absolute value, factorial, permutations (nPr), combinations (nCr), modulus, random integer, bell curve, cumulative normal distribution, decimal to fraction.

2) Graphing. Capabilities:

• Graph up to four equations at once.

• Graphs are labeled.

• You can drag the graph or pinch to zoom in or out.

• Calculator can find roots and intersections.

• Graph in polar coordinates.

• Graph parametric equations

3) A unit converter. With a tap, you can enter the result of your conversion into the calculator. Currently converts different units of the following: acceleration, angle, area, density, distance, energy, force, mass, power, pressure, speed, temperature, time, and volume. Great for doing physics homework!

4) Constants for scientific calculations -- speed of light, strength of gravity at Earth's surface, etc. etc. etc. Tapping on a constant will insert it into your calculation -- i.e, you don't have to key in the value. Again, great for doing physics homework!

5) It can make a table of the values of any function you care to enter. You can choose the starting x value of the table, as well as how much x increases for each successive row.

6) Forgot the quadratic formula? Or the double-angle formulas for sine and cosine? The math/science reference hits the high points of various subjects. Currently includes algebra, differential and integral calculus, geometry, trigonometry, vectors, vector calculus, and classical mechanics.

I'd love to hear your comments or suggestions. You can write me at the email address in the app. Thanks!

## Tips-kalkulator

Give a tip if the service was acceptable. Many employees in service industries have very little sallery. Without tips, these will be difficult to "make ends meet".

The generally accepted tip rate is somewhere between 15% and 20%.

If the service was terrible, you should not give a tip, but rather alert the management. If the service was slow, you should tip 10%. If the service was ok you should tip 15%, and if the service was good you should tip 20%.
