Answer 1

a.)18:2+16x9+9x3

=9+9x(16+3)

=9+9x19

=9+171

=180

b.)26x12-8x24

=312-192

=120

Answer 2

a)18÷2+16×9+9×3=9+16×9+9×3=9(1+16+3)=9×20=180.

b) 26×12-8×24=13×2×12-8×12×2=12×2(13-8)=24×5=120.

Answer 3

a/ 18:2+16x9+9x3

=9+16x9+9x3

=9x(1+16+3)

=9x20

=180

b/26x12-8x24

=26x12-8x12x2 =26x12-16x12

=12x(26+12)

=12x38

=458

Answer 5

Mấy bạn ơi phải là tính nhanh nhé chứ làm như các bạn chưa nhanh đau 

Answer 6

18 : 2 + 16 x 9 + 9 x 3

= 9 + 9 x ( 16 + 3 )

= 9 + 9 x 19

= 9 + 171 

= 182

26 x 12 - 8 x 24

= 312 - 192

= 120

Answer 7

a,18:2+16*9+9*3= 9+144+27=180

b,312-192=120

Answer 8

a) 18 : 2 + 16 x 9 + 9 x 3

= 9 x 2 : 2 + 16 x 9 + 9 x 3

= 9 x 1 + 16 x 9 + 9 x 3

= 9 x ( 16 + 3 + 1 )

= 9 x 20

= 180.

b) 26 x 12 - 8 x 24

= 26 x 12 - 8 x 2 x 12

= 26 x 12 - 16 x 12

= ( 26 - 16 ) x 12

= 10 x 12

= 120.

Answer 9

18:2 + 16x9+9x3

=9+9x(16+3)

=9x(1+16+3)

=9x20

=180

26x12-8x24

=26x12-8x24

=26x12-8x2x12

=26x12-16x12

=(26-16)x12

=10x12

=120

Answer 10

a, 18 : 2 + 16 x 9 + 9 x 3

= 9 + 9 x ( 16 + 3 )

= 9 + 9 x 19

= 9 + 171 

= 182

b, 26 x 12 - 8 x 24

= 312 - 192

= 120

Answer 11

a, 18 : 2 + 16 x 9 + 9 x 3

= 9 + 9 x ( 16 + 3 )

= 9 + 9 x 19

= 9 + 171 

= 182

b, 26 x 12 - 8 x 24

= 312 - 192

= 120

Answer 12
