Some of the other 40 iDevBooks math apps are Column Addition, Long Division, Long Multiplication, Lattice Multiplication, Visual Multiplication Table, Fraction Math, Partial Differences Subtraction, Partial Quotients Division, Partial Sums Addition, etc.  iDevBooks math apps have been reviewed and endorsed by Wired.com, IEAR.org, Edudemic.com, Teachers with Apps, and other respected sites and organizations.  "The Math apps by Esa Helttula allow students to practice and reinforce the specific computation strategies taught in class, with as much or as little scaffolding as necessary.  This math app can be used to teach and study the column subtraction method.  The user can solve random or custom subtraction problems with small and large numbers.  “With the ‘show current operation’ option turned on, they are constantly reminded of the next step, which can lead to efficient practice of the procedure.  The column subtraction method is also known as columnar subtraction, long subtraction or longhand subtraction.  Every time the user solves one addition problem, one more piece of a six-piece picture puzzle is revealed.  Then by turning off the current operation your child is able to practice remembering the steps on his/her own.  After solving the operation for each column the correct answer will fly to the right place.  You can also solve each step during the renaming by setting automatic renaming to off in the settings.  Pressing the rename-button carries out renaming which is animated step by step so you can see what happens.  The numbers are aligned automatically so that you can concentrate on solving the operations for each column.  They also provide individualized feedback to each student, with an immediacy that is not always possible through pencil and paper practice.  This app also does not contain any links to other apps or the web.  The app is easy to use and it has an intuitive interactive interface with customizable colors and other settings.  If the user presses the wrong button the answer will appear above the keyboard but it will not move.  Being able to adjust the level of difficulty to suit their needs is also very motivating for the students.  The picture puzzle feature can be turned off and on at any time.  This app has no ads or in-app purchases and it does not transmit any data during the operation of the app.  Renaming over several columns is also supported.  Please visit idevbooks.com to give feedback.  The number of digits in the numbers can be set.  The puzzles are pictures of cute animals.  New ideas to make this app better are welcome.
