0 + 330 = 510 + 230 = 20 + 780 = 290 + 290 = 130 + 600 = 350 + 50 = 740 - 40 = 20 + 430 = 950 - 60 = 850 - 70 = 220 + 510 = 10 + 160 = 300 + 370 = 180 + 600 = 370 + 320 = 460 + 500 = 790 - 290 = 580 + 260 = 750 + 0 = 10 + 700 = 210 + 220 = 640 + 360 = 510 - 0 = 400 + 420 = 660 + 90 = 850 - 0 = 550 - 240 = 510 - 230 = 210 + 650 = 780 - 540 = 470 + 200 = 320 + 210 = 800 - 470 = 130 + 600 = 720 - 590 = 570 - 10 = 880 + 50 = 80 + 790 = 990 - 550 = 330 + 450 = 920 - 550 = 260 + 240 = 250 - 170 = 340 - 210 = 290 + 500 = 680 - 60 = 10 + 280 = 990 - 780 = 890 - 480 = 780 - 460 = 580 - 190 = 280 - 40 = 180 + 550 = 80 + 130 = 70 + 110 = 290 + 380 = 490 - 390 = 520 + 220 = 530 + 60 = 60 - 50 = 970 - 390 = 70 + 590 = 970 - 120 = 900 - 480 = 950 - 170 = 400 - 10 = 180 + 530 = 460 + 50 = 250 - 190 = 550 + 380 = 530 + 420 = 990 - 500 = 790 - 340 = 680 + 60 = 210 + 610 = 50 + 140 = 610 - 460 = 390 + 560 = 550 + 360 = 270 - 20 = 250 + 640 = 170 + 340 = 330 - 310 = 220 + 190 = 30 + 20 = 960 - 300 = 220 + 710 = 330 + 500 = 680 - 500 = 270 - 120 = 10 + 540 = 590 + 140 = 250 + 200 = 590 + 100 = 890 - 640 = 320 - 130 = 960 - 120 =
160 + 260 =
700 - 150 =
490 + 290 =
二、填空
1.70里面有( )个十,260里面有( )个十. 2.600里面有( )个百,1200里面有( )个百. 3.14个十是( ),14个百是( ).

6.13个百减5个百是( )个百,写作( ). 三、口算下面各题
400+500= 200+400= 3000+4000= 800-500= 700-400= 7000-3000= 1200+3000= 400+2000= 4600+300= 1700-400= 7800-800= 3400-3000= 1200+6000= 2600+300= 4000+600= 9000-7000= 780-80= 2400-400= 60+90= 180-80= 2600+4000= 700+800= 240-60= 4700-3000= 500+900= 520-400= 1800-1000= 四、计算下面各题
400+600+700 1000-500+300 560-200-60 = = = = = =
700+3000-600 720-(140+60) 6000+(800-400) = = = = = = 五、应用题
