Răspuns:
a) 425 + ( 425 - 156 ) = 694 elevi
425 + 269 = 694
b) ( 8 × 10 ) : 5 = 16 cutii
80 : 5 = 16
c) 15 + ( 15 × 4 ) + ( 15 × 4 : 2 ) = 105 pagini
15 + 60 + ( 60 : 2 ) =
15 + 60 + 30 =
75 + 30 = 105
d) 500 - 100 - ( 2 × 38 ) - ( 100 : 2 ) = 274 lei
500 - 100 - 76 - 50 =
400 - 76 - 50 =
324 - 50 = 274
e) [ 700 - ( 98 × 3 ) - ( 99 × 4 ) ] : 5 = 2 rochii
( 700 - 294 - 396 ) : 5 =
( 406 - 396 ) : 5 =
10 : 5 = 2
