Answer:

8÷4+7-3 =6

8÷4+2-1 =3

6÷2+5-1 = 7

5÷1+6-2= 9

0÷5+4+3= 1

(1) The missing numbers are 2 and 5

(2) The missing numbers are 4 and 0

(3) The missing numbers are 6 and 8

(4) The missing numbers are 1 and 9

(5) The missing numbers are 7 and 3

The solution to the given problem is as follows;

In order of mathematical operation, we resolve division first before addition and finally subtraction.

In this problem we are to choose numbers from 0 to 9 and assume that no number will be repeated.

(1) (8 ÷ 2) + (5 - 3) = 6

⇒  4 + 2 = 6

so the missing numbers are 2 and 5

(2) (4 ÷ 4) + (2 - 0)= 3

⇒  1   +  2  = 3

so the missing numbers are 4 and 0

(3) (6 ÷ 2) + (6 - 1) = 8

⇒ 3 + 5 = 8

so the missing numbers are 6 and 8

(4) (5 ÷ 1) + (6 - 1) = 9

so the missing numbers are 1 and 9

(5)  (0 ÷ 7) + (4 - 3) = 1

so the missing numbers are 7 and 3

Thus, all the numbers from 0 to 9 have been used and non was repeated.
