四年级数学下册《小数的加法和减法》预习课件及练习题

1.小数数位相同的加减法(竖式计算)

5.5+4.5= 3.27-2.49= 11.65-7.39= 19.01-7.99=

7.51+0.49= 5.48-3.25= 4.8+18.9= 10.3+58.7=

8.03-4.56= 9.03-8.57= 4.17+2.53= 5.07-0.98=

5.67-0.73= 13.18+5.27= 5.16+7.89= 26.8+3.02=

6.07-4.993= 3.7+2.36= 15.4+2.97= 10.2-8.75=

7.81-3.735= 12.16+5.347= 0.4-0.125= 18.7+3.96=

9.6+4.78= 5.67-0.845= 0.506-0.19= 11.04-7.3=

1.4-0.405= 62.1-17.07= 1.4-0.405= 3.906+0.66=

43.5-27.34= 15.98-3.9= 75.6-3.55= 5.94+10.7=

12.03+0.87= 37.8+3.02= 0.704-0.25= 10.1-0.55=

10+10.1= 27+8.03= 26+7.98= 13.99+1=

7.88+2= 95-9.85= 20-9.42= 35.09-11=

96.85-85= 45.45-45=

2.小数加减混合运算(递等式计算)

5.03-2.5+0.96 22.8-5.23-9.125 23.66+4.34-3.56

5.6-0.81-1.29 15.9+3.26+4.17 67.2+41.5-71.39

10.75+0.4-9.473 16.23+8.92-7.56 50-28.5-13.45

13.79-9.653+170.57 1.5+0.68-0.306 72.8-8.6+5.84

20.8-(15.98-3.9) 32.5+(5.07+6.13) 3.52-(4.66-3.82)
