## Mental Arithmetic

There are two main modes (Singleplayer and Multiplayer)

In singleplayer mode you can improve your mental arithmetic skill and compare your skill with others or just train your simple math skills.

This app provieds three types of complexity (Easy,Average,I am genius) and for each type a set of exercise types.

Exercise types: Division, Addition, Subtraction, Multiplication, Mixed,Square Root (√x),Squaring (x²),Cubing (x³), Fraction Addition, Fraction Subtraction, Fraction Multiplication, Fraction Division, Fraction Mixed, Linear Eqations, Next Prime, Complex and much more.

It includes a Highscore for each complexity and exercise type. This Highscore is available online: http://mentalarithmetic.ctvnet.ch/

After a competition you can see your results to determine what was correct and what was wrong.

In the training mode you can set a custom number range for your questions.

the app supports App2sd for android 2.2 and greater.

In multiplayer mode you can challenge your friends directly!

You have to play 6 rounds alternately. The player who has more correct answers will win the game.

The time to answere is limited and it's multiple choice

There is a online ranking (http://mentalarithmetic.ctvnet.ch/ranking/) players who win a lot earns points, players who loose a lot looses points. players who give up loose automatically and loose points

Thank you for your feedback! We give our best to improve the app depending on your feedback.

Have fun!

## Arithmetic Operations

LXADAGG

1

Arithmetic operations is the ideal and free application to learn the basic arithmetic operations. Unlike other applications that assign your level by default, in this application you will be able to choose and adapt the level as you make progress.

Arithmetic operations allow:

-To choose the operation or operations you want to be asked and the operand ranks of each of them. You can save or load the default options by clicking on the menu button of your device.

-To choose the part of the operation you want to be asked: the result, the sign (if you want to choose more than one operation at the same time), or either of the operands.

-If you choose a division, you can select to be asked for the results with or without the remainder.

-You can choose to be asked a random operand considering the specified rank, or each of the values one by one. (That is ideal, for example, to learn a multiplication table).

-In case of failure, you can choose to be shown greater or less.

-In addition, there is an option to gather the result or make series from it.

-To make it easier, the device will be entering digits in the boxes (You can do it from right to left or the other way round, depending on whether you do it directly or add digit by digit.

-Individual statistics of each operation are included. You can save or restart them from the menu button.

-You can activate the chronometre and check the correct answer you make in sixty seconds, at any moment and regardless of the selected options.

-Languages: English and Spanish.

## Math Solver Mental calculation

The application is based on mathematical arithmetic and working with numbers and colors. Constant exercise will help you improve and maintain your mental faculties. Classes with the program will help you develop and strengthen logical thinking, numerical fluency, memory and mindfulness. Enhances mathematical skills on addition, subtraction, multiplication, division.

The program features three types of exercises.

* The first is the usual mathematical arithmetic. In this type of exercise, you need to calculate the mathematical expression in the mind. The complexity of the expression can be adjusted. An example of the expression: (23 * 12) + (434 / 14) to evaluate the expression we get the answer: 307. The decision is given unlimited time.

* The second exercise on the development of memory. In this type of exercise, you need to calculate mathematical expressions sequentially displayed on the screen. Each successive term is calculated based on the previous one. Complexity of expression and time display on the screen can be adjusted. Example order: "10 + 2", "X / 2", "X - 3". First calculate the first expression: 10 + 2 = 12. Then, in the second expression is substituted in place of X 12 and we get the expression: 12 / 2 = 6. Remember the answer: 6. The third expression is substituted in place of X 6 and obtain the expression: 6 - 3 = 3. The final answer: 3.

* The third exercise on the development of mindfulness. In this type of exercise, you need to calculate mathematical expressions sequentially displayed on the screen. The expression is shown for a short time - you need to have time to recognize and remember. Among the featured numbers you need to see a mathematical operator (use the "+" and "-"), the operator determines the color of significant digits, the remaining digits just distracting noise. Then the numbers are hidden - and you need to evaluate the expression. Each successive term is calculated based on the previous one. The complexity of the expression, the time display on the screen and the time allotted for the solution can be adjusted. Example of a "3 + 5 1 2", " - 5 1 1 2", "2 7 5 4 + ". At first look the color of the addition operator ("+" - say the color red), then in the expression, select all of the red numbers (for example it will be 3 and 1) - remember the result. In the second expression say the subtraction yellow ("-"), select all the yellow numbers (for example it will be 1 and 2) - evaluate the expression: 31 - 12 = 19 - remember the resulting number (19). The following terms are also looking for the addition ("+") and by its color, select all the figures of the same color (for example, it will be 2 and 5), and then evaluate the expression: 19 + 25 = 44. The final answer: 44.

This information can also be obtained in the help of program.
