Notes
This is the value matching the displayed symbol according to the coding dictionary presented on the screen. 
 To illustrate, the initial training screen displays 
 - [2,4,6,1,3,5,7,0] - code (upper) Array
- [7,1,5,4,6,0,3,2] - test (lower) Array 
 Then the leftmost picture in the test Array has value 7 (a crescent). In the upper code array the crescent appears above the numeral 7, so the value wanted here is 7. 
 The next item in the test Array has value 1 ("H" shape), which appears above the numeral 4 in the code array. 
 The last item in the test Array has value 2 ("=" symbol), which appears above the numeral 1 in the code array.
