Logical Instant is an entertainment which is basically a picture linked to a random number, obeying rules of the following arithmetic operations: sum, subtraction and multiplication.

    We present 4 pictures and 3 arithmetic operations (hidden) relating one to another resulting in a particular result.
     A From the type of arithmetic operation and the presented result, the player should identify the value of each picture, in a way that it has something to do with the result presented.

Example:

           Cat     ?    Car           = 5

           Horse  ?    House            = 20

           Cat     ?    House            = -3

    The player, as fast as possible, should find out the value of each picture and the arithmetic operation (?) solving all the operations presented.  
    For definitions purposes, all three arithmetic operations will always be shown. This way, if the first operation is a sum and the second a multiplication, the third shall be a subtraction.

    Notice that as an answer for each picture we will always give you 5 different options of numbers. Dealing with these options to solve the equations system, can make things easier.
    Important: All 4 numbers have to be different. In other words, the correct answer cannot repeat the same number.

    Scores:
    1. If the user does not get all 4 picture values right, he will not get any score, it does not matters how long it took him to answer it.
    2. The scores scale is modified every second obeying the following rule: 1000 times (.9885531 raised to the number of seconds that has passed).
Example:
The test was taken in 5 minutes (300 seconds). Then 1000 x (.9885531 raised to 300) = 31.62 (despise the decimals) = 31 If it was taken in 6 minutes (360 seconds). Then: 1000 x (.9885531 raised to 360) = 15.84 (despise de decimals) = 15

This formula allows the user to get a score if he takes the test within 10 minutes.
