Answer 1

Răspuns

33000 ;

Explicație pas cu pas:

a).  (800 - 147 :7 x 15 +10) x 67 - 168 +3=

( 800 - 21 x 15 +10 ) x67 -165 =

( 800 - 315 + 10 ) x67 -165=

495 x 67 - 165 =

33165 -165 =33000

b).  7000 - (1780 : 10 +1700 ) x3 + (40 : 5 x9 ) =

7000 - ( 178+1700) x3 + 8 x 9 )=

7000-1878 x 3 + 72=

7000-5634 + 72=1438
