Paso a paso

Answer 1

Respuesta:

a. 25 - 6 +19 + 78

= 19 + 19 + 78

= 38 + 78

= 116

__________________________________________________________

b. 185 + 984 - 234 - 74

= 1169 - 234 - 74

= 935 - 74

= 861

__________________________________________________________

c. (228-56) - (78+63) - 12

228 - 56

= 172

= 172 - ( 78 + 63) - 12

78 + 63

= 141

= 172 - 141 - 12

= 19

__________________________________________________________

d. 588 - (45 - 21) + (33-9)

41 - 21

= 24

= 588 - 24 + ( 33 - 9 )

33 - 9

= 24

= 588  - 24 + 24

= 564 + 24

= 588
