一、看谁算得快（每道题2分，共60分）

14 – 3 = 2 + 15 = 15 – 3= 13 – 2 = 14 + 0 = 9 + 5= 18 – 6= 14 – 3 = 1 0 – 8 = 15 – 3 = 17 – 2 = 14+3 = 15 – 4 = 16 – 3 = 10 – 7 = 19 – 5 = 18 – 6 = 10–8 = 18 – 4 = 9 + 8= 7 +1 2 = 18–3= 19 – 7 = 12 + 5 = 5 + 13 = 19 – 2 = 18 – 5 = 3 +15 = 6 + 12 = 8 + 11 =

二、计算小能手（每题2分共40分）

18 – 5 +3 = 17 – 4 + 1 = 12 + 2 – 4 =

16 – 5 + 8= 4 + 13 + 2 = 16 +2– 5= 11 – 1 – 5= 18 – 4– 3 = 15 – 2 – 1 = 10 – 3 – 6 = 11 + 4 + 5 = 3 + 3 + 12 = 19 – 5 – 4 = 4 + 15 – 3 = 13 + 6 – 4 = 17 + 2 – 5 = 10 – 6 – 2 = 12 +3+ 5 = 9 + 8– 4 = 19 – 7 + 2 =
