9 4 6 2 = 12

12⬜️5⬜️10⬜️3 =2

5⬜️14⬜️7⬜️2 = 6

10⬜️12⬜️16⬜️5 =13

7⬜️3⬜️2⬜️8 = 15

9⬜️12⬜️2⬜️3 = 7

Answer 1

9 × 4 : 6 × 2 = 36 : 6 × 2 = 6 × 2 = 12 

12 × 5 : 10 : 3 = 60 : 10 : 3 = 6 : 3 = 2 

5 + 14 : 7 : 2 = 5 + 2 : 2 = 5 + 1 = 6 

10 - 12 : 6 + 5 = 10 - 2 + 5 = 8 + 5 = 13 

7 x 3 + 2 - 8 = 21 + 2 - 8 = 23 - 8 = 15 

9 - 12 : 2 : 3 = 9 - 6 : 3 = 9 - 2 = 7 

Answer 2

(9 × 4 : 6)× 2 = 12
12 ×5: 10 : 3 = 2
(5+ 14 -7): 2 = 6
10+ 12 - 16+ 5 = 13
7 × 3 + 2- 8 = 15
9-( 12: 2: 3 )= 7
