解:
(1)103×0.8,
=(100+3)×0.8,
=100×0.8+3×0.8,
=80+2.4,
=82.4;
(2)3.15×100-3.15,
=315-3.15,
=311.85;
(3)3.15×99,
=3.15×(100-1),
=3.15×100-3.15,
=315-3.15,
=311.85;
(4)5.9×3.3+5.9×7.7,
=5.9×(3.3+7.7),
=5.9×11,
=64.9;
(5)5.9×(3.3+7.7),
=5.9×11,
=64.9;
(6)100×0.8+3×0.8,
=80+2.4,
=82.4;
(7)5.36+4.38-2.36,
=9.74-2.36,
=7.38;
(8)5.36-2.36+4.38,
=3+4.38,
=7.38.
