1. 看谁算得又快又准。
900 + 1000 = 6000 + 2000 = 600 + 400 =
40 + 400 = 280 - 80 = 2000 + 3000 =
700 + 100 = 900 - 800 = 6000 - 5000 =
7000 - 4000 = 5000 + 1000 = 500 + 7000 =
400 + 3000 = 680 - 80 = 9000 - 6000 =
550 - 50 = 350 - 300 = 8200 - 200 =
8200 - 8000 = 700 + 20 = 400 + 1000 =
8000 - 4000 = 50 + 300 = 4300 - 300 =
620 - 20 = 400 + 2000 = 600 - 600 =

答案： 1. 1900 8000 1000 440 200 5000 800 100 1000 3000 6000 7500 3400 600 3000 500 50 8000 200 720 1400 4000 350 4000 600 2400 0
