(12 + 17 - 15): (2 + 5) =
(35 – 10) : (17- 9 - 3) =
(16 - 8) (2 x 3 + 1) =
(4 + 16): 4 + (5 + 3) * 7 =
(12 – 3 X 4) (27 - 21) =
8:04 + 7 – 3) + 9 * 5 = 1​

Answer 1

Răspuns:

(12 + 17 - 15): (2 + 5) =

(29-15):7=

14:7=

2

(35 – 10) : (17- 9 - 3) =

25:5=

5

(16 - 8) (2 x 3 + 1) =

8×7=

56

(4 + 16): 4 + (5 + 3) * 7 =

20:4 + 8×7=

5 + 56=

61

(12 – 3 X 4) (27 - 21) =

(12-12)×6=

0×6=

0

(8:04 + 7 – 3) + 9 * 5 =

2+4+45=

51

Explicație pas cu pas:

Answer 2

( 12 + 17 - 15 ) : ( 2 + 5 ) =

( 29 - 15 ) : 7 =

14 : 7 = 2

( 35 - 10 ) : ( 17 - 9 - 3 ) =

25 : ( 8 - 3 ) =

25 : 5 = 5

( 16 - 8 ) × ( 2 × 3 + 1 ) =

8 × ( 6 + 1 ) =

8 × 7 = 56

( 4 + 16 ) : 4 + ( 5 + 3 ) × 7 =

20 : 4 + 8 × 7 =

5 + 56 = 61

( 12 - 3 × 4 ) × ( 27 - 21 ) =

( 12 - 12 ) × 6 =

0 × 6 = 0

( 8 : 4 + 7 - 3 ) + 9 × 5 =

( 2 + 7 - 3 ) + 45 =

( 9 - 3 ) + 45 =

6 + 45 = 51
