Question

1用简便方法计算+4.83.6-3.83.6+0.1259380？

Answer 1

这都是一些基础题，学会多分析，计算功底好了，以后数理化才能如履薄冰。

Answer 2

0.125×9.3×80
=0.125×80×9.3
=10×9.3
=93
4.8×3.6-3.8×3.6
=(4.8-3.8)×3.6
=1×3.6
=3.6
0.8×0.6+0.32
=0.8×0.6+0.8×0.4
=0.8×(0.6+0.4)
=0.8
9.9×13.6
=(10-0.1)×13.6
=10×13.6-0.1×13.6
=136-1.36
=134.64

Answer 3

大概是问第1题第3小题
4.8＊3.6-3.8＊3.6
=(4.8-3.8)＊3.6
=3.6
