a) \(\left(-1\right)\left[5^2-\left(4^3\right)\right]=\left(-1\right)\left(25-64\right)=\left(-1\right)\left(-39\right)=39\)
b) \(71.64-32.\left(-7\right)+32.11=142.32+32.7+32.11\)
\(=32.\left(142+7+11\right)=32.\left(142+18\right)=32.160=5120\)
c) \(666-\left(-422\right)-100-88=666+422-100-88\)
\(=\left(666+422\right)-\left(100+88\right)=1088-188=900\)
d) \(23-501-343+61-257+16-499\)
\(=\left(23+61+16\right)-\left(501+499\right)-\left(343+257\right)\)
\(=100-1000-600=100-\left(1000+600\right)=100-1600=-1500\)
