a =  \binom{1 \:  \:  \:  \: 2 \:  \:  \: \:  3}{2 \:  \:  \: 3 \:  \:  \: 1}  \:  \:  \: and \:  \:  \: b =  \binom{3 \:  \:  \:  - 1 \:  \:  \: 3}{ - 1 \:  \:  \: 0 \:  \:  \: \: 2}  \\ now \:  \: 2a - b = 2 \binom{1 \:  \:  \: 2 \:  \:  \: 3}{2 \:  \:  \: 3 \:  \:  \: 1}  -  \binom{3 \:  \:  \:  - 1 \:  \:  \: 3}{ - 1 \:  \:  \: 0 \:  \:  \: 2}  \\  =  \binom{2 \:  \:  \: 4 \:  \:  \: 6}{4 \:  \:  \: 6 \:  \:  \: 2}  -  \binom{3 \:  \:  \:  - 1 \:  \:  \: 3}{ - 1 \:  \:  \: 0 \:  \: \:   \: 2}  \\  =  \binom{ - 1 \:  \:  \: 5 \:  \:  \: 3}{5 \:  \:  \: 6 \:  \:  \: 0}
