Respuesta:

a) ( -3 ) + ( –2) – ( –5 ) – ( +3) – ( –10) =

-3 -2 +5 -3 +10 = - 8 + 15 = +7

b) ( +10) – ( –12) + ( –3 ) – ( –10 ) + ( –20 )=

+10 +12 -3 +10 -20 = + 32 - 23 = +9

c) ( –12 ) + ( –15 ) – ( –23) + ( +18) – ( –9 ) + ( –15 ) =

-12 -15 +23 +18 +9 -15 = -42 +50 = +8

d) ( –7 ) – ( –16) + ( –5) – ( –12) + ( –8 ) – ( +15 ) – ( –3 ) =

-7 +16 -5 +12 -8 -15 +3 = -35 +31 = -4

Explicación paso a paso:

Answer 2

Respuesta:

a) ( -3 ) + ( –2) – ( –5 ) – ( +3) – ( –10)

   -3 -2 +5 -3 +10 = 7

b) ( +10) – ( –12) + ( –3 ) – ( –10 ) + ( –20 )

    10 +12 -3 +10 -20 = 9

c)  ( –12 ) + ( –15 ) – ( –23) + ( +18) – ( –9 ) + ( –15 )

   -12 -15 +23 +18 +9 -15 = 8

d) ( –7 ) – ( –16) + ( –5) – ( –12) + ( –8 ) – ( +15 ) – ( –3 )

   -7 +16 -5 +12 -8 -15 +3 = -4

e) ( –9 ) + ( –8 ) + ( –15 ) – ( +17 ) – ( –32 )=

   -9 -8 -15 -17 +32 = -17

Recuerda usar la ley de signos cuando las hagas por ti mismo

- ( - ) = +

+ ( + ) = +

-  ( + ) = -

+ ( - ) = -
