Question

Calculeaza repetând parantezele a) 275:5+(21+81:9)= b)(59-24:6):5+628:2=. c) 8*7:[10-(13-25:5)]​

Answer 1

275 : 5 + ( 21 + 81 : 9 ) =

55 + ( 21 + 9 ) =

55 + 30 = 85

( 59 - 24 : 6 ) : 5 + 628 : 2 =

( 59 - 4 ) : 5 + 314 =

55 : 5 + 314 =

11 + 314 = 325

8 × 7 : [ 10 - ( 13 - 25 : 5 )] =

56 : [ 10 - ( 13 - 5 )] =

56 : ( 10 - 8 ) =

56 : 2 = 28
