( 5.876 - 1.893 ) - ( 86 × 4 + 78 ) =

3.983 - ( 86 × 4 + 78 ) =

3.983 - ( 344 + 78 ) =

3.983 - 422 = 3.561

235 × 2 + ( 86 × 8 + 102 ) =

235 × 2 + ( 688 + 102 ) =

235 × 2 + 790 =

470 + 790 = 1.260

7.890 - ( 135 × 6 + 27 × 9 ) =

7.890 - ( 810 + 27 × 9 ) =

7.890 - ( 810 + 243 ) =

7.890 - 1.053 = 6.837

( 10.000 - 100 × 100 ) + ( 973 × 10 × 0 ) =

( 10.000 - 10.000 ) + ( 973 × 10 × 0 ) =

0 + ( 9.730 × 0 ) =

0 + 0 = 0
