6. Martin en total leyó 3/6

Explicación paso a paso:

1. a) {-25 * [6*(23-56)]  +[20÷(10*(-90))]}

       {-25 * [6*(-33)  +[20÷(-900)]}

       {-25 * (-198) + (-0.02)}

        4,949.98

  b) {49- (-12 * 25) * [35* (-56 + 35)]} * (29 -35) ÷ (-3)

      {49- (-12 * 25) * [35* (-21)]} * (29 -35) ÷ (-3)

      {49- (-300) * (-735)} * (29 -35) ÷ (-3)

      220,549 * (29 -35) ÷ (-3)

       220,549 * (-6) ÷ (-3)

       441,098

2. 12 - 15 = -3

3.    2 + 8 + 3 - 5 - 6 = 2

6. 2/3 + 1/6 = 3/6
