5.9 10.1的简便运算

5.9*10.1=5.9*(10+0.1)=5.9*10+5.9*0.1=59+0.59=59.59 把10.1可以看成(10+0.1).利用乘法分配率.再进行简便运算.

5.9乘以10.1=5.9*(10+0.1)=59+0.59=59.59

10.1*5.9=(10+0.1)*5.9 =10*5.9+0.1*5.9=59+0.59=59.59

5.9x10.1=5.9x10+5.9x0.1=59+0.59=59.59

5.9*10.1-5.9 = (6-0.1)*(10+0.1)-(6-0.1) =60+0.6-1-0.01-6+0.1=60+ 0.6+0.1- 6-1 -0.01

5.9*10.1=5.9*(10+0.1)=5.9*10+5.9*0.1=59+0.59=59.59

0.59x10.1=0.59x10+0.59x0.1=5.9+0.059=5.959

7.3*4.5-4.5 =(7.3-1)*4.5=6.3*4.5=28.355.9*10.1=5.9*10+5.9*0.1=59+0.59=59.59

2.6*10.1=2.6*10+2.6*0.1=26+0.26=26.26

5.7*(10+0.1)=57+0.57=57.57
