Answer 1

[(5+3)x(9+7)]:2=(8+16):2=128:2=64
{[(9+7x3):(5x5-15)]+[(8+9)x(6x4)]}=[(30:10)+(17x24)]=3+408=411;
[(9x9):(3x3)]=81:9=9;
12+[(15+4x3)-(9+3x6)]=12+(27-27)=12;
{[(5x3):(9:3)]+[(1+3x2)-(2x2+2)]}=](15:3)+(7-6)]=5+1=6;
(6x9):(5+4)=54:9=6;
{[(3x3)+(2x9)]:(3+3)}=(9+18):9=27:9=3;
[(1+1)+(15x4)]-3=(2+60)-3=62-3=59;
(6:2)x(12+45)=3x67=201;
[(6+7)+(5x6)]-43=(13+30)-43=43-43=0;
(5x5+10):7=35:7=5;
4+{[(6+7)-5]:(8x3-20)}=4+[(13-5):(24-20)]=4+(8:4)=4+2=6;
