Developer Chat with Esa from iDevBooks




Q.  Hi Esa. Welcome to AppAbled. Can you please tell us a little bit about yourself and how you got into the App business?

A. I live in Finland and I started to program computers 35 years ago at high-school when our math teacher bought the school an Apple II computer. The teacher started to teach programming to volunteers. I went on to study engineering and computer science and became an algorithm visualisation researcher. I have also taught computer science to teens and adults. I love mathematics and that is why all of my apps are about mathematics.

Q. When was iDevBooks founded ?

A. iDevBooks was founded in 2007.

Q. Is there a story behind the choice of the name ?

A. To make a long story short I will just say that I had the domain for another reason and decided that it was a good name.

Q. How long does it take you to develop each app ?

A. I have now 23 apps and I’m working on several apps at the same time. I can think about a mathematics subject for a year before implementing it as an app. But in a way, none of my apps are ready yet. Yes, they are on the App Store but I have updated them almost 100 times with new features. Right now I’m working on an update for my second app (Column Subtraction) that I released over three years ago. A teacher wanted a new feature and I agreed that it would be a good feature. I see apps as works in progress. It is impossible to know what the future holds. I had 15 apps when the iPad was introduced and it took me over a year to redesign and update all of my apps with new custom interfaces for the iPad.

Q. What does iDevBooks have in store for us in the future?

A. More updates and more apps.

Q. How many people do you have working at iDevBooks?

A. I’m the only person working at iDevBooks.

Q. Do you have a favourite iDevBooks app?

A. That would be Visual Multiplication Table. 

Q. Who Beta Tests your apps for you?
  
A. My wife and daughter are good testers.

Q. Is there anything you would like to add? 

A. I would like to thank the AppAbled community for great comments and feedback during this week that I have been developer of the week. It has been such a nice experience.

Partial Quotients Division

Requirements: Compatible with iPhone, iPod touch, and iPad. Requires iOS 4.3 or later. This app is optimized for iPhone 5.

Description

This math app can be used to teach and study the partial quotients division method. The app is easy to use and it has an intuitive interactive interface with customizable colours and other settings. The user can solve random and custom division problems.
he Partial Quotients Division Method

The traditional long division method can be difficult to understand because it is so abstract. In the partial quotients method the student can make a series of estimates and then add the estimated quotients together. 

In the example 992/8 the first estimation can be 100, which leaves 192. Next estimation can be 20 which leaves 32. Now the student knows that 8 goes 4 times into 32 and the result can be found by adding up the partial quotients 100, 20 and 4. Each student can use the quotients that he or she finds the easiest.

In the Everyday Mathematics curriculum the partial quotients division method is the focus algorithm for division.

The App is Easy to Use

After the user solves each operation or inputs a new estimate, the correct answer will fly to the right place. If the user presses the wrong button or gives an impossible estimate the answer will appear above the keyboard but it will not move. 

The App Has The Following Settings

- The dividend can have from 2 to 5 digits
- The divisor can have 1 or 2 digits
- Random and custom problems
- The current operation can be hidden
- The operands of the current operation can be highlighted
- Colours of the interface can be changed
- The speed of the animations can be set

The column division method is a simple variation of the traditional long division method. Lines are drawn to separate the digits of the divisor. Each place-value column is solved from left to right.

In the Everyday Mathematics curriculum the column division method is one of the algorithms for division.
