Answer 1

1. 324-628:4+99= 324-157+99=266
 2. 609:3+3:(60-57)=203+3:3=203+1=204
 3. (609-599)X3-3:(4X120-477)= 10X3-3:3=30-1=29
4. (420:10+469)-(130:5+141-2X55)=(42+469)-(26+141-110)=511-57=401
5. [(704+7X8)-(576:3+64):8]:4= [(704+56)-(192+64):8]:4=(760-256:8):4=(760-32):4=728:4=182
 6.19+2X14+3X[2+3X(45-95:5)]=19+28+3X[2+3X(45-19)]=47+3X(2+3X26)= 47+3X(2+78)=47+3X80=47+3X80=47+240=287
7. [(7X3-5)+2X6:4+5]X10-[(4+9)X5-60]=[(21-5)+3+5]X10-[13X5-60]=(16+8)X10-(65-60)=24X10-5=240-5=235
8. 700:2:7+824:4:2-515:5+816:8=50+103-103+102=152
 9. [124X7-36X5+(310X2-500)]-798=[868-180+(620-500)]-798=(688+120)-798=808-798=10
10. 800-[(100+100:10)X2]+(200+120:2-0)=800-[(100+10)X2]+(200+60)= 800-(110X2)+260=800-220+260=800+40=840
