96-{10+4[-3+8-(11-15) (10-6)]}

96-{10+4[-3+8-(11-15) (10-6)]}  .....  whew!!!!   Let's simplify this

Working inside the parentheses, we have

96-{10 + 4[-3 + 8- (-4) (4)]}      next, work within the brackets......  remember to carry out multiplication before addition or subtraction !!!

96-{10 + 4[-3 + 8 + 16]}        add/subtract within the brackets

96-{10 + 4[21]}                     now, work within the braces

96-{10 + 84}

96 - {94}  =

2

Mmmmmm...all that work for just 2  !!!!!!
