Math Arrow matrix is a visual tool designed to make the relationship among numbers more intuitive and to enhance the learning of mathematical functions. It was created by economist and author Todd Buchholz, a former White House economic adviser and winner of the Allyn Young Teaching Prize at Harvard University. [1]
Unlike a number line, which extends horizontally and infinitely, the Math Arrow displays the whole numbers from 0 to 100 in a pair of parallel zigzag lines. [2] The numbers on the left hand zigzag run from 0 at the bottom to 50 at the top; on the right hand zigzag they run from 50 at the top to 100 at the bottom (the number 50 appears twice, at the top of both zigzags). The Math Arrow has a number of characteristics that allow users to detect patterns in the relationship of numbers.
The tool is supported by an iPad app that is aimed at 3 to 13 year-olds. There are three difficulty levels to span those ages. [3]
The Math Arrow was invented by economist and author Todd Buchholz, a former White House economic adviser and winner of the Allyn Young Teaching Prize at Harvard University. Buchholz developed and patented the Math Arrow in conjunction with his daughters Victoria, Katherine and Alexia. The Math Arrow is used in games developed by the educational software company, Sproglit, LLC, of which Buchholz is a founder and serves as chief executive officer. [4]
In an article for the Huffington Post, Buchholz wrote: "Sometimes we need to fundamentally re-examine even the basic tools of the classroom. Take the number line, which hangs on the walls of kindergartens across the world. Why is it horizontal? Are we sure that this linear image is the most effective way to demonstrate relations among numbers? What if it had a different shape, for example, a zig-zag? Innovations in design can help develop math sense in our children and teach them in a way that engages and plays to their love of images." [5]
In 2013, a number of schools in San Diego and Utah began using Sproglit’s first game, Kyle Counts as an iPad App in beta form.
The Math Arrow has been called "ingenious" by Martin Cooper, inventor of the cellular phone. It has also been praised by Caltech physicist Len Mlodinow, who co-wrote with Stephen Hawking, A Briefer History of Time and The Grand Design. [6]
Commenting on the invention, The Guardian's Alex Bellos wrote: "The point behind Todd's reinvented number line is a valid and interesting one: that visual memory needs to be exploited far more than it currently is when we learn numbers. [...] Professional mathematicians will often tell you that the only way they can fully understand certain abstract concepts is by creating a visual image. So why not encourage children to do the same with numbers?" [7]
Education Today highlighted the fact that Math Arrow is not the only product of its kind on the market, but said "unlike other maths apps, it does not rely on drilling facts in a way that soon bores young children". [8]
Dance Dance Revolution (DDR) is a music video game series produced by Konami. Introduced in Japan in 1998 as part of the Bemani series, and released in North America and Europe in 1999, Dance Dance Revolution is the pioneering series of the rhythm and dance genre in video games. Players stand on a "dance platform" or stage and hit colored arrows laid out in a cross with their feet to musical and visual cues. Players are judged by how well they time their dance to the patterns presented to them and are allowed to choose more music to play to if they receive a passing score.
The sawtooth wave is a kind of non-sinusoidal waveform. It is so named based on its resemblance to the teeth of a plain-toothed saw with a zero rake angle. A single sawtooth, or an intermittently triggered sawtooth, is called a ramp waveform.
2 (two) is a number, numeral and digit. It is the natural number following 1 and preceding 3. It is the smallest and only even prime number. Because it forms the basis of a duality, it has religious and spiritual significance in many cultures.
666 is the natural number following 665 and preceding 667.

iWork is an office suite of applications created by Apple for its macOS, iPadOS, and iOS operating systems, and also available cross-platform through the iCloud website.
224 is the natural number following 223 and preceding 225.
Spreadsheet is a class of application software design to analyze tabular data called "worksheets". A collection of worksheets is called a "workbook". Online spreadsheets do not depend on a particular operating system but require a standards-compliant web browser instead. One of the incentives for the creation of online spreadsheets was offering worksheet sharing and public sharing or workbooks as part of their features which enables collaboration between multiple users. Some on-line spreadsheets provide remote data update, allowing data values to be extracted from other users' spreadsheets even though they may be inactive at the time.

SpicyNodes was a system for displaying hierarchical data, in which a focus node displays detailed information, and the surrounding nodes represent related information, with a layout based on radial maps. It has web (Flash) and mobile (iOS) implementations. It has ended operation as of 1 January 2018
Word Lens was an augmented reality translation application from Quest Visual. Word Lens used the built-in cameras on smartphones and similar devices to quickly scan and identify foreign text, and then translated and displayed the words in another language on the device's display. The words were displayed in the original context on the original background, and the translation was performed in real-time without a connection to the internet. For example, using the viewfinder of a camera to show a shop sign on a smartphone's display would result in a real-time image of the shop sign being displayed, but the words shown on the sign would be the translated words instead of the original foreign words.
