|In the example 3 from c1 can be 3=2+1 or 3=1+2, because you can only use digits from 1 to 9 the only valid solution is 11=9+2, so b2=9, c2=2, b3=7 & c3=1. (a2=b2+c2=9+2=11)|
|In the example 4 from d2 can be 4=3+1 or 3=1+3, because you can only use digits from 1 to 9 the only valid solution is 11=8+3, so e2=1, f2=3, f3=8. (f1=f2+f3=3+8=11)|
|In the example 3 from g5 can be 3=2+1 or 3=1+2, because you can only use the same digit once in a columb the only valid solution is 4=3+1, so g6=2, g7=1, f6=4 & f7=3 (g5=g6+g7; f5=f6+f7 & e7=f7+g7)|
|In the example 3 from c5 can be 3=2+1 or 3=1+2, because 2 was used in the same colum (g6), the only valid colution is 3=1+2, so c6=1, c7=2 & d7=6. (c5=c6+c7 & b7=c7+d7)|
|In the 6th column 21-(1+4+2)=14; 14=5+9=6+8; 16=1+2+4+6 => 14=6+8 => 16=8+6. d6=8, e6=6.|
|27-(7+1+8)=27-16=11; 11=2+9(can't be because of row 6)=3+8(8 apears in column 3)=4+7(7 apears in column 3)=5+6(6 apears in line d)=9+2 => d3=9, e3=9.|
