Me pueden ayudar a resolver estos ejercicios por favor

Answer 1

EJERCICIO 3 :

resuelve paso a paso y agrupando

a) 2 - 4 - 5 + 8 = - 2 - 5 + 8 = - 7 + 8 = +1

b) 6 - 7 + 4 - 3 = - 1 + 4 - 3 = 3 - 3 = 0

c) 5 + 8 - 9 - 6 = 13 - 9 - 6 = 4 - 6 = - 2

d) - 4 - 9 + 6 + 2 = - 13 + 6 + 2 = - 7 + 2 = - 5

e) - 3 - 5 + 7 + 7 = - 8 + 7 + 7 = - 1 + 7 = 6

f) - 4 - 8 - 2 - 5 = - 12 - 2 - 5 = - 14 - 5 = - 19

EJERCICIO 4 :

calcula las siguientes restas de números enteros

( + 10 ) - ( - 14 ) = ( + 10) + ( 14 ) = 24

( - 8 ) - ( - 16 ) = ( - 8 ) + ( + 16 ) = 8

( + 4 ) - ( - 14 ) = ( + 4 ) + ( + 14 ) = 28

( + 12 ) - ( - 19 ) = ( + 12 ) + ( + 19 ) = 31

( - 13 ) - ( + 15 ) = ( - 13 ) - ( - 15 ) = - 28

( + 21 ) - ( - 18 ) = ( + 21 ) + ( + 18 ) = 39

( - 15 ) - ( - 18 ) = ( - 15 ) + ( + 18 ) = 3

( + 17 ) - ( - 16 ) = ( + 17 ) + ( + 16 ) = 33

( + 25 ) - ( - 46 ) = ( + 25 ) + ( + 46 ) = 71

( - 31 ) - ( - 32 ) = ( - 31 ) + ( + 32 ) = 1

( - 59 ) - ( - 18 ) = ( - 59 ) + ( + 18 ) = 41

( + 62 ) - ( - 71 ) = ( + 62 ) + ( + 72 ) = 134
