(9+87) x6:07 + 89) =
1200 + (712:2 + 3) - 913 =
(15609:3+ 19300) - 17319:3=​

Answer 1

1200 + (712:2 + 3) - 913 =

= 1200 + 356 + 3 - 913 =

= 1559 - 913 = 646

(15609:3 + 19300) - 17319:3 =

= 5203 + 19300 - 5773 =

= 24403 - 5773 =

= 18730

(9+87)*607 + 89 =

= 58272 + 89 =

= 58361

Nu prea am inteles la primul, X6:07, dar am presupus *607 ^^
