Answer 1

Răspuns:

Explicație pas cu pas:

24: 8 x 3 x 4 :6 =

= 3 x 3 x 4 :  6 =

= 9 x 4 : 6 =

= 36 : 6 = 6

30 +32 : 8 +8 x7- 100: 10 =

=30 + 4 + 56 - 10 = 80

20-(3 x5 –2 +3 ):(26 –9 x 2)=

= 20 - ( 15 - 2 + 3 ) : ( 26 - 18 ) =

= 20 - 16 : 8 =

= 20 - 2 = 18

10 x 4 :5 x 3 + 32-32:8 x7 =

= 40 : 5 x 3 + 32 - 4 x 7 =

= 8 x 3 + 32 - 28 =

= 24 + 32 - 28 = 28

89 + 64:8x7- 28:7 x 4 =

= 89 + 8 x 7 - 4 x 4 =

= 89 + 56 - 16 = 129

(25: 5-7:7) +(36:9 +8 x0)=

= ( 5 - 1 ) + ( 4 + 0 ) =

= 4 + 4 = 8

815-24:2:2=

= 815 - 12 : 2 =

= 815 - 6 = 809

50:10:5+90:9=

= 5 : 5 + 10 =

= 1 + 10 = 11

12+6:(3+9:3)=

= 12 + 6 : ( 3 + 3 ) =

= 12 + 6 : 6 =

= 12 + 1 = 13

21-21: 7x(4 - 5: 5)=​

= 21 - 21 : 7 x ( 4 - 1 ) =

= 21 - 21 : 7 x 3 =

= 21 - 3 x 3 =

= 21 - 9 = 12
