Answer 1

1. 1000-[(70+130):2]= 1000-(200:2)= 1000-100= 900
2. 642-(7×7+8×9)+3×8= 642-(49+72)+24= 642-121+24= 545
3. 6786×32-32+320×3+[50+300×3+[50+300×(200×3+5)]= 6785x32+320x3+182500=400580
4. 27×103+7207:26-69= 2781+277,19-69= 2989,19
5.126×292:7+1549-39:13= 5256+1546=6802
6. {[860:43+800)×7]×77}:11= 40180
