In the previous post, I have shared to you the advantages of using Wolfram Alpha. In this post, I am going to list some of the basic calculations that can be done using the same app. Note that you can use these commands both in the iOS version or the web version.
1. Do Basic Arithmetic with Integers, Fractions, and Decimals
150 + 32
1200 – 3
15.8 * 2.5
1/5*(3 – 8)
2. Compute Decimal Approximation to a Specified Number of Digits
It’s been a while since I have written about GeoGebra, but I have started updating some of the tutorials to GeoGebra 5. For those who have not explored the Archives, I have written numerous GeoGebra tutorialsranging from basics to advanced.
GeoGebra is now version 5.0. New features were added and a lot of improvementshad been made. The 3D is now stable and 4 new tools were added. The Insert Image tool now support SVG files. But aside from these, there are simple updates which I really like and I think teachers will also love them. Here are four of them.
1.) Automatic Color Change
Every time you graph a new function in the current version of GeoGebra, it automatically selects a different color. You don’t have to trouble yourself changing the color of the graph of the new functions. » Read more
Last week, I wrote about a tutorial on how to create math expressions in a Google Forms using Latex. Embedding of Latex in Google Docs documents can be made using the new g(Math) Google Docs Add On. Although Google Docs has a built in equation editor, the addition of Latex through g(Math) can make embedding of more complicated equations possible.
In addition to Latex, you can also create graphs using g(Math). Once you have added this add on, you can create graphs using the side bar of your Google Docs window.
Watch John McGowan, creater of g(Math), demonstrates how to use g(Math) on Google Docs.
For those who are not familiar with Latex, it is a typesetting system used to create scientific documents. It can also be used to create complicated math expressions. You can read my introduction andbrief tutorial about latexin case you don’t know about it.
