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 index 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 index 1 (an "H" shape), which appears above the numeral 4 in the code array.

The last item in the test Array has an index 2 (an "="), which appears above the numeral 1 in the code array.
