Math: Long Division 1.103
The application will teach you how to do a long division. Theapplication is smart: it tries to understand your mistakes and giveyou appropriate indications. The long division is a fundamentalconcept of math. It includes the division of course, but also themultiplication, the subtraction and the multiplication tables, allmath operations. Mastering the long division means mastering allthese technics of math. The application proposes two modes:training and learning. In learning mode, the application shows youhow to do the long division step by step. Each step of the mathexercise is explained and detailed. You can choose the numbers,divisor and dividend, or let the application randomly choose thedivision to do. In training mode, you do the long division step bystep by yourself. The application detects the mistakes, such asforgetting the carry. It gives you indications if you need allalong math exercises. Several levels are possible for mathexercises. The easy level proposes simple numbers, for the earlylearning of division. The following levels proposes more and moredifficult exercises. One can choose between integer long divisionor decimal numbers, with or without intermediate subtraction. Theapplication computes a score from time and mistakes during thedivision. This gives you motivation to train and let you see theprogression in the long division. Note: The application uses vocalsynthesis (it speaks) to comment the division during mathexercises. On some devices, it will propose to you to installupgrades of vocal synthesis if you want to get better dictionquality.
Math: Long Multiplication 18.0
The application will teach you how to do a long multiplication. Theapplication is smart: it tries to understand your mistakes and giveyou appropriate indications. The long multiplication is afundamental concept of math. Long multiplication is one of thebasis of all the skills developed in arithmetics and in math ingeneral. And it makes you learn and consolidate multiplicationtables. The application proposes two modes: training and learning.In learning mode, the application shows you how to do the longmultiplication step by step. Each step of the math exercise isexplained and detailed. You can choose the numbers, or let theapplication randomly choose the long multiplication to do. Intraining mode, you do the long multiplication step by step byyourself, and you train multiplication table by the way. Theapplication detects the mistakes, such as forgetting the carry. Itgives you indications if you need all along math exercises. Severallevels are possible for math exercises. The easy level proposessimple numbers, without carry : you just use multiplication tables.The following levels proposes more and more difficult exercises, inparticular using the carry. The application computes a score fromtime and mistakes during the long multiplication. This gives youmotivation to train and let you see the progression in the longmultiplication. Practicing math is important ! Note: Theapplication uses vocal synthesis (it speaks) to comment the longmultiplication during math exercises. On some devices, it willpropose to you to install upgrades of vocal synthesis if you wantto get better diction quality.

Mathematics : Brain Training 1.4
Train your brain with mathematic operations.The principle is verysimple: on the one hand the app proposes a target number, and onthe other hand it gives you some operation symbols together with acollection of digits. Then you have to reconstruct the operation toget the number.This exercise is excellent for training in mentalcomputation. Doing it is a very good practice for mathematics, forall the arithmetic operations: addition, multiplication, divisionand subtraction.There are several levels. The first ones are veryeasy, ideal if you are learning to count. And step by step, itintroduces more and more difficulties, becoming an excellent braintraining.
