Răspuns:

Explicație pas cu pas:

68 × 5 - ( 484 : 2 + 963 : 3 + 866 : 2 ) : 3 = 8

= 340 - ( 242 + 321 + 433 ) : 3 =

= 340 - 996 : 3 =

= 340 - 332 =

= 8

( 770 : 7 + 699 : 3 + 686 : 2 ) : 2 - 999 : 3 = 10

= ( 110 + 233 + 343 ) : 2 - 333 =

= 686 : 2 - 333 =

= 343 - 333 =

= 10

122 × 5 - ( 468 : 2 + 848 : 2 + 666 : 6 + 888 : 8 ) : 2 : 2 = 390

= 610 - ( 234 + 424 + 111 + 111 ) : 2 : 2 =

= 610 - 880 : 2 : 2 =

= 610 - 440 : 2 =

= 610 - 220 =

= 390

75 × 5 - ( 648 : 2 + 555 : 5 + 462 : 2 + 999 : 3 ) : 3 = 42

= 375 - ( 324 + 111 + 231 + 333 ) : 3 =

= 375 - 999 : 3 =

= 375 - 333 =

= 42
