A) 4-7+7-8-9-12+6=
[tex]=-3+7-8-9-12+6\\\\=4-8-9-12+6\\\\=-4-9-12+6\\\\=-13-12+6\\\\=-25+6\\=-19[/tex]
B) 4(-5+7)-8-(-3-7)+(6+7)=
[tex]=4\cdot \:2-8-\left(-3-7\right)+\left(6+7\right)\\\\=4\cdot \:2-8-\left(-10\right)+\left(6+7\right)\\\\=4\cdot \:2-8-\left(-10\right)+13\\\\=8-8-\left(-10\right)+13\\\\=23[/tex]
C) 3[-8+6(5-4+7-2)+(6+4+5): (7-4)=
[tex]=3\cdot \:33\\\\=99[/tex]
D) 3{ 3+(4+6X3)+4[2-8(5-2)-8]+2(2+3)}=
[tex]=33+4+6X\cdot \:3+4\left(2-8\left(5-2\right)-8\right)+2\left(2+3\right)\\\\=33+4+18X-120+2\left(2+3\right)\\\\=33+4+18X-120+10\\\\=18X+33+4-120+10\\\\=18X-73[/tex]
