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.
