1. Realizar los siguientes ejercicios combinados:
a. {(-5 + 4) * (-2) + [4 - (-9) = (3)] + (-10) - (2)}
b. {[(-8 + 6-3) * (-3) + 5] = (+5) - (-12+4) = (8)}
c. {[-12 + (-8 + 5) * (-3)] = [(-10) = (-5) - 3]}
d. {(-10 + 7 + 6) * (-5) + [8 - (-9) + (-3) - 6] * (-4)
e. {[12 - 6 (-3)] = (6) + (-5 + 7) * (4) + 9 = (-3)
f. {[(13 - 5) (-8) + 9] * (3) - 28 = (4)}
g. {[9 - (-3) - (6) * (-4)] * (-4) + 15 = (-3) + (-6-3) * (2)}
h. {4 + [3 * (-5) + (10 - 7)] 4 - 2
i. { -3 + {(-6) * 5 - [3 + (-8 + 5) * (-2)] + (-12) + (6)}}
j. { (-9) = (3) + [ 19 - 10 = (+ 5)] * (-3+5) + 6 * (-8)}
