Answer 1

分析 根據(jù)整數(shù)加減法運(yùn)算的計(jì)算法則計(jì)算即可求解．

解答 解：

47-11=36	26-18=8	52-49=3	74-66=8	40-21=19
50-35=15	46-25=21	43+35=78	14+22=36	53+15=68
50-25=25	35+35=70	21+30=51	43-13=30	60-25=35
64+12=76	22+24=46	43+36=79	64+20=84	59-14=45
78-26=52	59-33=26	78-26=52	95-80=15	55-45=10
87-6=81	52+18=70	62+38=100	55+45=100	54+8=62
56+23=79	14+75=89	64+16=80	45+27=72	95-26=59
59+16=75	43-15=28	48+22=70	64-46=18	87-49=38
66+14=80	35-26=9	38+24=62	98-41=57	85-22=63
100-65=35	70-36=34	450+60=510	40+800=840	390+100=490

點(diǎn)評 考查了整數(shù)加減法運(yùn)算，關(guān)鍵是熟練掌握計(jì)算法則正確進(jìn)行計(jì)算．
