15 - 9 =        16 - 1 =        18 - 10 =       12 + 3 - 8 =  
16 - 9 =        11 + 2 =        8 + 8 =        19 - 8 + 7 =  
12 - 8 =        13 - 9 =        7 + 3 =        13 - 8 + 6 =  
7 + 8 =         15 - 8 =        11 - 9 =        12 + 0 - 8 =  
2 + 17 =        17 - 8 =        14 - 9 =        11 + 5 - 8 =  
11 - 8 =        9 + 8 =         10 - 8 =        17 - 8 - 8 =  
8 + 4 =         18 - 9 =        14 + 4 =        14 - 8 - 2 =  
16 - 8 =        8 + 3 =         9 + 10 =        5 + 6 - 8 =  
19 - 10 =       5 + 9 =         18 - 8 =        4 + 6 + 9 =
