( 3 × 12 + 16 ) : 26 = 2
= ( 36 + 16 ) : 26 =
= 52 : 26 =
= 2

40 + 10 × { 32 : 4² + 5 × [ 20 - 4 × ( 125 : 5 - 7 × 4 ) ] } = 1 660
= 40 + 10 × { 32 : 16 + 5 × [ 20 - 4 × ( 25 - 28 ) ] } =
= 40 + 10 × { 2 + 5 × [ 20 - 4 × ( - 3) ] } =
= 40 + 10 × [ 2 + 5 × ( 20 + 12 ) ] =
= 40 + 10 × ( 2 + 5 × 32 ) =
= 40 + 10 × ( 2 + 160 ) =
= 40 + 10 × 162 =
= 40 + 1 620 =
= 1 660
