Answer 1

{[(5-5)+5]-5}:5=1
{[(5x5):5]-5}+5=5
{[(5-5):5]+5}+5=5

Answer 2

a)

( 5 + 5 ) : 5 - 5 : 5 = 1

= 10 : 5 - 1 =

= 2 - 1 =

= 1

b)

5 + 5 + 5 - 5 - 5 = 5

= 15 - 5 - 5 =

= 10 - 5 =

= 5

sau:

5 : 5 + ( 5 - 5 : 5 ) = 5

= 1 + ( 5 - 1 ) =

= 1 + 4 =

= 5

sau:

5 × 5 : 5 + 5 - 5 = 5

= 25 : 5 + 5 - 5 =

= 5 + 5 - 5 =

= 10 - 5 =

= 5

c)

5 × ( 5 : 5 + 5 : 5 ) = 10

= 5 × ( 1 + 1 ) =

= 5 × 2 =

= 10
