Answer 1

18+3*[15-15/(4/4+2)+16*9]=18+3*[15-15/(1+2)+16*9=18+3*(15-15/3+16*9)=18+3*(15-5+144)=18+3*154=18+462=480

Answer 2

18+3x[15-15:(4:4+2)+16x9]=18+3x[15-15:(1+2)+16x9]=18+3x[15-15:3+16x9]=18+3x[15-5+144]=18+3x[10+144]=18+3x155=18+465=483;  2000+{11x[20:4x(2+2:2)+1]+27:3x11}=2000+{11x[20:4x(2+1)+1]+27:3x11}=2000+{11x[20:4x3+1]+27:3x11}=2000+{11x[5x3+1]+27:3x11}=2000+{11x[15+1]+9x11}=2000+{11x16+99}=2000+{176+99}=2000+275=2275;  400+[24:(8+2:2-1)+16:4]-22x9=400+[24:(8+1-1)+4]-198=400+[24:8+4]-198=400+[3+7]-198=400+10-198=410-198=212
