Answer 2

(18×11)+(297:3)=198+99=297
(998:2)+(505:5)=499+101=600
350-(6×18):3=350-(108:3)=350+36=385
b) 175-(175:25)×15=175-(7×15)=175-105=70
395+(52:52)×7=395+(1×7)=395+7=402
(600:10)+(270:9)=60+30=90
c) (600:10):2+(125:5)-(270:9)=(60:2)+25-30=25
300-(123×4):(6:1)+(88×4)=300-(492:6)+352=300-82+352=570
1200+(456×12)-(780:20)×(40:1)=1200+540-(39×40)=1200+540-1560=180
sunt clasa a||| a si noi asa procedam,punem parantexe si respectam ordinea efectuarii operstiilor,daca am gresit ceva scuze,calculele sunt ok
