Explicație pas cu pas:
a) 33 333 × 184 + 33 333 × ( - 84)
-> il dau factor comun pe 33 333
= 33 333 × ( 184 - 84) =
= 33 333 × 100 =
= 3 333 300

b)
757 × 1023 + 757 × ( -23) =
= 757 × ( 1023 - 23 ) =
= 757 × 1000 =
= 757 000

c)
44 444 × ( - 24 ) + 44 444 × 96 + 44 444 × ( - 72) =
= 44 444 × ( - 24 + 96 - 72) =
= 44 444 × ( 72 - 72 ) =
= 44 444 × 0 =
= 0

d)
( 4 + 44 + 444 + 4 444 + 44 444 ) : 2 + 24 : 12 : ( - 1 - 11 - 111 - 1 111 - 11 111) =
= 4 × ( 1+11+111+1 111+11 111) : 2 + 2 : ( - 1 ) × ( 1+11+111+1 111 + 11 111) =
= 2 × ( 1+11+111+1 111+11 111) - 2 × ( 1+11+111+1 111+11 111) =
= 0
