Explicație pas cu pas:

2×{189+432:3·[225-200:(0,16:0,04+1,875·3,2)+132,5·(365,5-28,2·3)]+1}=

= 2 ×{189 + 144×[ 225 - 200 : ( 4 + 6 ) + 132,5 ×(365,5 - 84,6)] + 1} =

= 2 × [ 189 + 144 × (225 - 200 : 10 + 132,5 ×280,9 ) + 1] =

= 2 × [ 189 + 144 × (225 - 20 + 37219,25 ) + 1 ] =

= 2 × ( 189 + 144 × 37424,25 + 1 ) =

= 2 × ( 190 + 5 389 092 ) =

= 2 × 5 389 282 =

= 10 778 564
