Once upon a time ( erase una vez, había una vez ...) a man tries to rob a bank in the middle of the night ( en mitad de la noche) When the police tries to arrest him, the thief cuts his head with a blade. A month later, when one of the policemen is sleeping, the thief appears in his dream, and he can't resist to cut his head too. All the policemen finish cutting their heads.

PROPIEDAD DISTRIBUTIVA: la suma de dos sumandos, multiplicada por un número, es igual a la suma del producto de cada sumando por ese número.

( b+c) a = (b.a) + (c.a) = ( 8+6) 4 = ( 8.4) + ( 6.4 ) 14 . 4 = 32 + 24 56= 56

( b-c) a = (b.a) -( c.a) = ( 8 - 6) 4 = ( 8.4) - ( 6 . 4)

2.4 = 32 - 24 8 = 8
