Answer 1

13 - 13 : ( 1 + 2 × (( 65 - 70 : 5 × 4 ) : 3 + 32 : 8 ) : 7 × 6 ) =

13 - 13 : ( 1 + 2 × (( 65 - 56 ) : 3 + 32 : 8 ) : 7 × 6 ) =

13 - 13 : ( 1 + 2 × (( 65 - 56 ) : 3 + 4 ) : 7 × 6 ) =

13 - 13 : ( 1 + 2 × ( 9 : 3 + 4 ) : 7 × 6 ) =

13 - 13 : ( 1 + 2 × ( 3 + 4 ) : 7 × 6 ) =

13 - 13 : ( 1 + 2 × 7 : 7 × 6 ) =

13 - 13 : ( 1 + 2 × 6 ) = 13 - 13 : 13  = 13 - 1 = 12

Answer 2

Răspuns: 12 => rezultatul

Explicație pas cu pas:

13 - 13 ÷ {1 + 2 × [(65 - 70 ÷ 5 × 4) ÷ 3 + 32 ÷ 8] ÷ 7 × 6} = 12

13 - 13 ÷ {1 + 2 × [(65 - 14 × 4) ÷ 3 + 4] ÷ 7 × 6} = 12

13 - 13 ÷ {1 + 2 × [(65 - 56) ÷ 3 + 4] ÷ 7 × 6} = 12

13 - 13 ÷ [1 + 2 × (9 ÷ 3 + 4) ÷ 7 × 6] = 12

13 - 13 ÷ [1 + 2 × (3 + 4) ÷ 7 × 6] = 12

13 - 13 ÷ (1 + 2 × 7 ÷ 7 × 6) = 12

13 - 13 ÷ (1 + 14 ÷ 7 × 6) = 12

13 - 13 ÷ (1 + 2 × 6) = 12

13 - 13 ÷ (1 + 12) = 12

13 - 13 ÷ 13 = 12

13 - 1 = 12
