Answer 1

25 - { 54 : [( 24 - 18 : 3) : 2 ] + 54 : 9 × 3 } =

= 25 - { 54 : [( 24 - 6 ) : 2 ] + 6 × 3 } =

= 25 - [ 54 : ( 18 : 2 ) + 18 ] =

= 25 - ( 54 : 9 + 18 ) =

= 25 - ( 6 + 18 ) =

= 25 - 24 =

= 1

Answer 2

25–{54:[(24–6):2]+54:9·3}=

25–[54:(18:2)+54:9·3]=

25–(54:9+54:9·3)=

25–(6+18)=

25–24=1
