四、计算.（每题2分，共28分)
18+9 - 9 = 12 - 8 + 70 = 70 — 30 + 6 = 46 + 40 + 2 =
99 — 9 — 40 = 5 + 70 - 5 = 9 + 7 + 20 = 14 - 5 + 30 =
30 + 6 + 4 = 55 — 5 + 15 = 36 +30 +20= 5 + 5 5 +20=
13 - 5 + 50= 82 — 80 +8= 98— 20-8= 25+60+5=
58+4 ＝ 71—6 ＝ 5 +78＝ 35+5 ＝ 41+9 ＝ 98—90= 93—9 =
5 +37＝ 5 +82＝ 60—9 ＝
41-8 ＝ 46+3 ＝ 46+7 ＝ 53—20＝
84+6 ＝ 85—4 ＝ 29—3 ＝ 49+9 ＝
84—5 ＝ 8 +59＝ 37-5 = 50+46＝
69+8 ＝ 64-40＝ 7 +28＝ 46—9 ＝
45—6 ＝ 59+7 ＝ 59+5 ＝ 81+9 ＝
16+8 ＝ 76—50＝ 87-5 ＝ 36+8 ＝
37+9 ＝ 31-8 ＝ 67—6 = 27+3 ＝
46+8 ＝ 5 +47＝ 4 +27＝ 90+8 ＝
25+7 = 26+8 = 45—8 = 54-8 +8 ＝
