Install Basic Math Decoded
You can install Basic Math Decoded from the file you downloaded. Just double click on the file and follow the requested steps if you agree the License Agreement.
Start Basic Math Decoded
Once the program has been successfully installed, you can run it, using the icon on your desktop, or by searching the folder “Basic Math Decoded” in the All Programs menu in the start menu, and clicking on the link to the executable file “Basic Math Decoded”.
The period of evaluation is 10 days; after this time you must enter your ID and serial number provided by Nibcode solutions inc. when purchasing the licence.

Math operators and numbers types
To solve a problem and get the step by step solution, you only have to select the tab associated to the math operation; later you must choose the numbers type you want to use, and enter the numbers.
Basic Math Decoded performs the following operations: Addition, Subtraction, Multiplication and Division; on whole numbers, fractions, mixed numbers and decimals.
Results sheet
All the outputs are shown in the result sheet. For each problem, it will be written: the calculation to solve, the stepbystep solution, and comments, explanation as well as some recommendations. At each step, the digits involved are highlighted in red or bold, in order to a better understanding of the procedure to be carried out.
Games
Basic Math Decoded has 3 games designed as a complement for the studying and practicing the basic math operations. Each game has 3 complexity levels: easy, medium and hard.
Fast calculation
In order to make operations with big numbers is necessary to know by heart the onedigit numbers operations. The main goal of this game is to evaluate, by means on entertainment and randomly, if you master this basic calculations.
20 calculations will be shown when you start a new game, which depends on the operation and level you selected. The calculation to solve is shown in the blue rectangle, placed in the top centre, and you must select the plane with the right answer. In the upper left corner there is a chronometer indicating the elapsed time, and to the left the amount of right and wrong answers. Planes move at different speed which varies for every calculation, and when you select a wrong plane, it will explode, consuming an additional time.
Select the wrong answer
This game has some points in common with the first one, but it takes a greater mastery of the calculations to be learned by heart, because a total of 10 mathematical operations will be presented in each exercise, involving the four basic operators. One of the answers is wrong, and you must select it. One you have chosen your answer, you must click on the button Next to go to the next exercise.
A total of 20 exercises will be shown, whose complexity depends on the selected level. In the upper right corner there is a chronometer indicating the elapsed time, and to the left the amount of right and wrong answers.
Fill blank spaces
The purpose of this game is to fill some blank spaces, in the result of calculation involving whole numbers with several digits. Depending on the selected operation and level, it will be shown the result of a calculation with some blank spaces which should be filled. This game is a little more complicated than the two others, and to solve it, you need to master the calculation procedures. Problem solutions can be determined in a unique way. To check if the answer is correct, click on the button Check, and it will show the amount of right (green font) and wrong cells (red font). When there is at least one wrong cell, you will get the possibility to see the right solution for all the cells.
Options
Basic Math Decoded offers several options for personalizing the software.
Decimal places to show at least when dividing decimal numbers: When dividing decimals numbers, the quotient is shown with as many decimal places as the maximum between the decimal places of the dividend and the divisor. If that number is less than the specified value in this option, then this value will be used as the amount of decimal places in the quotient.
Long multiplication format: Choose, from the two most common long multiplication formats, the one you want to use.
Long division format: Choose, from the two most common long division formats, the one you want to use.
When changing the problem, show the last saved entry: If this option is checked, every time an operation or numerical set is selected, the last data entry, associated to the current selection will be shown in the input controls.
Clear the result sheet before showing the solution for a new problem: Clear the results sheets every time a new problem is solved, showing uniquely the current problem solution.
Languages
Basic Math Decoded has been designed for Multilanguage support. The default language is English, but the distribution contains the Spanish as an alternative language too. Other languages can be incorporated, just by translating the file associated to one of the existing languages and copying the translated file with extension “.lgg” to the Language folder, located in the directory where the program was installed. When the program starts, it scans this folder and shows the file names as submenu items of the submenu Language in the main menu. Selecting one of these items, the associated language will be automatically loaded and it will be kept as current language each time the program starts.
Translating a language file
The option “Save selected language to a file” allows saving selected language text into a text file, in order it can be translated to other language of your preference, to be loaded by the program subsequently.
The format of the language file is as follows:
[1]
0=Addition
1=Subtraction
2=Multiplication
…
[3]
0_1=Numbers have only one digit…
0_2=Place one number above the other, so that…
0_3=Add the digits {1}. The sum is more than 10, regroup…
0_4=Add the digits {1} and place the answer below the…
…
Numbers in squared brackets “[” and “]” are the sections, number before each line are the keys of the sections, and text after the equal symbol “=” is the value associated to the key.
This format allows translating the text directly in any translation service, keeping the sections and the keys. If the text is too big, just translate it by parts, keeping in mind that the equal symbol in each line must be after the key. You must be careful, that the curly brackets and the numbers within them (example: {1}) are kept intact and in position, because they are interpreted by Basic Math Decoded as parameters to be evaluated when text is going to be shown. Evidently the translations will not be perfect but is a good starting point.
