递等式计算.
| 15.73-(2.17+0.73)-1.83 | (339-67)×15÷24 |
| 64×(12+65÷13) | 8.37+5.95一(6.52+3.44) |
(1)15.73-(2.17+0.73)-1.83,
=15.73-2.17-0.73-1.83,
=(15.73-0.73)-(2.17+1.83),
=15-4,
=11;
(2)(339-67)×15÷24,
=272×15÷24,
=4080÷24,
=170;
(3)64×(12+65÷13),
=64×(12+5),
=64×17,
=1088;
(4)8.37+5.95-(6.52+3.44),
=14.32-9.96,
=4.36.
