1: \(2155-\left(174+2155\right)+\left(-68+174\right)\)
=2155-174-2155-68+174
=(2155-2155)+(174-174)-68
=-68
2: \(-25\cdot72+25\cdot21-49\cdot25\)
\(=25\left(-72+21-49\right)\)
\(=25\cdot\left(-100\right)=-2500\)
3: \(35\left(14-23\right)-23\left(14-35\right)\)
\(=35\cdot14-35\cdot23-23\cdot14+23\cdot35\)
\(=35\cdot14-23\cdot14=12\cdot14=168\)
4: \(8154-\left(674+8154\right)+\left(-98+674\right)\)
=8154-674-8154-98+674
=(8154-8154)+(674-674)-98
=0+0-98
=-98
5: \(-25\cdot21+25\cdot72+49\cdot25\)
\(=25\left(-21+72+49\right)\)
\(=25\cdot100=2500\)
6: \(27\left(13-16\right)-16\left(13-27\right)\)
\(=27\cdot13-27\cdot16-16\cdot13+16\cdot27\)
\(=27\cdot13-16\cdot13=11\cdot13=143\)
7: -1911-(1234-1911)
=-1911-1234+1911
=-1234
8: \(156\cdot72+28\cdot156\)
\(=156\cdot\left(72+28\right)\)
\(=156\cdot100=15600\)
9: \(32\cdot\left(-39\right)+16\cdot\left(-22\right)\)
\(=16\cdot\left(-78\right)+16\cdot\left(-22\right)\)
\(=16\cdot\left(-78-22\right)=16\cdot\left(-100\right)=-1600\)
10: -1945-(567-1945)
=-1945-567+1945
=-567
11: \(184\cdot33+67\cdot184\)
\(=184\cdot\left(33+67\right)\)
\(=184\cdot100=18400\)
12: \(44\cdot\left(-36\right)+22\cdot\left(-28\right)\)
\(=22\cdot\left(-72\right)+22\cdot\left(-28\right)\)
\(=22\cdot\left(-72-28\right)=22\cdot\left(-100\right)=-2200\)
