(2)(5) - (-2) ÷ [(4)(5) + (-2)]   Multiply (2)(5)
  10 - (-2) ÷ [(4)(5) + (-2)]   Multiply (4)(5)
   10 - (-2) ÷ [(20) + (-2)]   Simplify the double negative
    10 + 2 ÷ [(20) + (-2)]   Add 20 + (-2) = 20 - 2
           10 + 2 ÷ 18         Add 10 + 2
               12 ÷ 18          Divide 12 ÷ 18
                   \frac{12}{18}   Simplify
                   \frac{2}{3}
