The aim of this App is add all the Math exercises of The Mental Calculation World Cup in one place to train your Mental Math Skills .
This App was part of mental training App Called EMVM ("Entrenador multiple de velocidad mental" in english: Multiple Trainer of Mental Velocity). This software trains a different part of the mind in every second or less with basic task looking for velocity responses. If you do not answer the question in the stipulated time the App change the question. For example first question is of logic then you answer yes or no and the App pops up another question of math, etc. If your are slow the App changes the question and set up a new easy velocity to the task. If your answer is correct the App adjust then less time for the next question for that type. In the developing I added more complex tasks (mainly Math tasks) that require minutes to by solved for example a multiplication of 8 digits numbers losing the initial spirit of one of two second or less task and change the region of mind trained with a new question.

Now all Math exercises of EMVM are transferred to this App. This App originally coded in PHP is now optimized for run in electron. The App is now translated to English.
You can do different exercises and mix them all.
