1. 看谁算得又快又准。
600 - 500 = 9000 - 4000 = 400 + 90 =
5000 - 2000 = 7000 + 2000 = 100 + 300 =
900 - 500 = 400 + 5000 = 2300 - 300 =
500 + 300 = 600 + 3000 = 600 - 300 =
30 + 200 = 300 + 7000 = 4300 - 4000 =
3000 + 500 = 5500 - 500 = 8000 - 5000 =
2000 + 100 = 600 - 400 = 250 - 200 =
800 + 4000 = 200 + 400 = 700 + 300 =
4700 - 700 = 3000 + 100 = 5000 + 5000 =

答案： 1. 100 5000 490 3000 9000 400 400 5400 2000 800 3600 300 230 7300 300 3500 5000 3000 2100 200 50 4800 600 1000 4000 3100 10000
