Your last example works if you add some brackets

echo (  0                // n = -1
        + (s[0]=="."?2:4)  // n = 0 so should be 4
        + (s[1]=="."?2:4)  // n = 1 so should be 4
        + (s[2]=="."?2:4)  // n = 2 so should be 2
        + (s[3]=="."?2:4)  // n = 3 so should be 4
    ); // Outputs "ECHO: 14"
