Question

23 - 20:2 + 4 x 8 + 7 x7-74 +g
= 4 x 6
(2 x 2 + 2 - 2:2 x2) x (2 x 2-2:1) Xh= 8 x 8:8 x 10
63: 7+27:3-(48 + 8): (11-3) = 1 + 9​

Answer 1

23 - 20 : 2 + 4 × 8 + 7 × 7 - 74 + g = 4 × 6

23 - 10 + 32 + 49 - 74 + g = 24

13 + 32 + 49 - 74 + g = 24

45 + 49 - 74 + g = 24

94 - 74 + g = 24

20 + g = 24

g = 24 - 20

g = 4

( 2 × 2 + 2 - 2 : 2 × 2 ) × ( 2 × 2 - 2 : 1 ) × h = 8 × 8 : 8 × 10

( 4 + 2 - 1 × 2 ) × ( 4 - 2 ) × h = 64 : 8 × 10

( 6 - 2 ) × 2 × h = 8 × 10

4 × 2 × h = 80

8 × h = 80

h = 80 : 8

h = 10

63 : 7 + 27 : 3 - ( 48 + 8 ) : ( 11 - 3 ) = 1 + 9

9 + 9 - 56 : 8 = 10

18 - 7 = 10

11 = 10

11 > 10
