(-12 ) + (+15) =
(-7 ) + (+3 ) =
(-8 ) + (-7 ) =
(+13 ) + (+8) =

(+14 ) + ( -12) =
(+4 ) + (- 16) =
( 0 ) + (-3 ) = (+4 ) + ( 0 ) =


2. Indica las sumas que son incorrectas.


-2 + 4 = +2
-4 +1 = -3
-8 +3 = +5
-12 +5 = -7

-7 – 9 = -2
-4 –3 = -7
+16 – 8 = -24
-7 +16 = -9​

Answer 1

Respuesta:

LOS QUE NO TIENEN SIGNO SON LOS QUE SON POSITIVOS ( + ) PORQUE YA SE SOBRE ENTIENDE.

(-12 ) + (+15) = 3

(-7 ) + (+3 ) = -4

(-8 ) + (-7 ) = -15

(+13 ) + (+8) = 21

(+14 ) + ( -12) = 2

(+4 ) + (- 16) = -12

( 0 ) + (-3 ) = -3

(+4 ) + ( 0 ) = 4

2. Indica las sumas que son incorrectas.

-2 + 4 = +2 V

-4 +1 = -3 V

-8 +3 = +5 F

-12 +5 = -7 V

-7 – 9 = -2 F

-4 –3 = -7 V

+16 – 8 = -24 F

-7 +16 = -9​ F
