Answer 1

4 × 8 + ( 174 + 249 - 68 ) × 0 = 32 + 0 = 32 
          → aplic proprietatea inmultirii: Produsul e 0, cand unul din factori e 0!

( 81 : 9 ) + ( 7 × 8 - 6 × 9 ) - ( 301 - 292 ) = 2 
= 9 + ( 56 - 54 ) - 9 =
= 9 + 2 - 9 =
= 2 

( 2 × 3 × 1 + 72 : 9 ) : 7 = 2
= ( 6 + 8 ) : 7 =
= 14 : 7 =
= 2


200 - 100 : 10 + 1 × 7 × 8 × 0 - ( 45 + 45 ) = 100
= 200 - 10 + 0 - 90 =
= 190 - 90 
= 100


543 - 4 × 10 - 10 × 10 - ( 129 + 174) = 100
= 543 - 40 - 100 - 303 =
= 503 - 100 - 303 =
= 403 - 303 =
= 100


100 - ( 549 - 421 - 9 × 9 + 3 × 7 ) = 32 
= 100 - ( 128 - 81 + 21 ) =
= 100 - ( 47 + 21 ) =
= 100 - 68 =
= 32 


( 36 : 4 + 25 : 5 - 7 × 2 ) × 8 × 9 = 0
= ( 9 + 5 - 14 ) × 8 × 9 =
= ( 14 - 14 ) × 8 × 9 =
= 0 × 8 × 9 =
= 0


( 264 - 198 + 367 ) × 2 × 0 × 5 = 0
