Answer 1

Explicación paso a paso:

Antes de empezar recordemos la ley de signos:

(-)×(-)=(+)

(+)×(-)=(-)

(-)×(+)=(-)

a. ( + 5 ) – ( - 6 )

=( + 5 ) – 1 ( - 6 )

=( + 5 ) + 6

= 11

b. (+ 5 ) – ( + 6 )

= 5 - 6

= - 1

c. ( - 5 ) – ( - 6 )

= - 5 + 6

= 1

d. ( - 5 ) – ( + 6 )

= - 5 - 6

= - 11

e. ( - 3 ) – ( + 9 )

= - 3 - 9

= - 12

f. ( - 3 ) – ( - 9 )

= - 3 + 9

= 6

g. ( + 3 ) – ( + 9 )

= 3 - 9

= - 6

h. ( + 3 ) – ( - 9 )

= 3 + 9

= 12
