Answer 2

[(271-169):2(280+120):4]x2=(102:2x400:4)x2=20400:4x2=5100x2=10200

24x{100:[412-(317+90)]}=24x[100:(412-407)]=24x(100:5)=24x20=480

{100-[99+999-(1000-1)]:9}:89=[100-(99:9)]:89=(100-11):89=89:89=1

{400+6000:[66-540:(6x7-33)]x8}:7=[400+6000:(66-540:9)x8]:7=(400+6000:60x8]:7=(400+800):7=1200:7=171

4+5x{36:9+0x[10+3x(330:5-72:2)]}=4+5x4=4+20=24

20+2{32x8+4[20+4(800:5-36:2)]}=20+2[32x8+4(20+4x142)]=20+2(32x8+4x588)=20+2(256+2352)=20+5216=5236

150+{450:5+25:5[975-(50:5+3)x75]}x2=150+[450:5+25:5(975-13)x75]x2=150+(450:5+25:5x962x75)x2=150+(90+360750)x2=150+360840x2=150+721680=721830

288+819:9+4[20+6x(245:5-246:6)]=2808+91+4(49-41)=2899+4x8=2899+32=2931

56+5{64:8+4[40+7(300:5-72:2)]}=56+5[64:8+4(40+7x24)]=56+5(64:8+4x208)=56+5x840=56+4200=4256
