Calculators That I Use Nowadays

I have shared several decent calculators and graphing tools in this blog, but in this post, I’m going to share the calculators that I actually use nowadays. The calculators I use depend on the task that I’m doing. I use my phone for short and simple calculations, but if I’m studying or working for an hour or more, I use an actual calculator to avoid distractions. Here are the four calculators that I use most of the time.

1.) Calculator (Mac)

When I’m using my laptop, I use the default calculator app of MacOS. This app allows the user to choose among basic, scientific, and programmable modes. It also supports base 8, base 10, and base 16 number systems. Personally, I only use the basic and scientific calculators and I have not tried the programmable calculator yet. 

2.) Google’s Calculator App (Android)

Google’s calculator is a simple and beautifully designed app for basic calculations and scientific calculations. It can store previous calculations. I like the simplicity of this app, so I use it most of the time for basic calculations when I’m using my Android phone. This app is compatible with WearOS.

3.) Advanced Calculator FX991 (Android). This is a paid app but I really like it because it mimics the interface of an actual calculator (see image below). I’ve been using it for six months and so far, I really liked it.

4.) Casio FX991 ES Plus. Aside from apps, I also keep a Casio 991ES Plus. It’s not that I wanted to buy this calculator,  but it was the only decent calculator in a store the time when I wanted to buy one. So far, so good, I’ve gotten used to it. I think I will be using it for a long time.

That’s all. Maybe you can share the calculators that you’re using in the comment section below.

 

Google launches AR Measure app

One of the interesting app I’ve came across recently is Google’s AR Measure App. This app allows you to use your phone camera to pick two points in the real world and get the distance between them. You can use either imperial or metric units in measurement. In addition, you can also save photos for later measurements. For approximating the height of a cabinet or the length of the table, this app can come in handy. And from experience, it’s quite accurate. I tried to measure my Macbook Pro and I was only 1 centimeter off.

Google Measure

Although I have already tried the app in measuring short lengths, I would like to try measuring long ones. I think this can be very useful in teaching trigonometry and trigonometry. For example, we can make students solve for trigonometry problems and then use the app to check if their answer is correct. That is, of course, assuming that the app is accurate at measuring long distances.

Google AR Measure is available for free in Google Play for Android phones that support Google’s ARCore platform. There is an interesting competition though. Apple has the same app which has the same name.

 

Editing of Old Articles

Mathematics and Multimedia has been silent for the past four months because I am busy, but I have silently edited old articles. I will continue editing and one of the improvements that I am planning is to integrate GeoGebra applets in some of the articles since GeoGebra can now be directly embedded in WordPress posts. As many of you already know, I have numerous tutorials on how to use GeoGebra. In addition, I am also updating the tutorials using the current version of GeoGebra. There are many new developments particularly the integration of augmented reality.

I started this blog 9 years ago and, so far, I have written more than 1000 articles. Many of them are on using GeoGebra and many also contains discussion about mathematics content from elementary school to university mathematics. Numerous times, I have also introduced apps that can be used for teaching and learning mathematics. The complete list of all the posts can be found in the Archives page.

Starting today, I will be sharing more about mathematics teaching and mathematics ago. I had been hesitant to share my thoughts about them because I felt that I was not qualified to do so. Recently, I have realized that maybe, there are a few things that I can share from more than one and a half decades of teaching and training. Hopefully, this blog will be of help to younger teachers or at the very least a trigger for reflection and discussion.
