35x6-70x3+35

Answer 1

35 x 6 - 70 x 3 + 35

= 35 x 6 - 35 x 2 x 3 + 35

= 35 x 6 - 35 x 6 + 35

= 35 x ( 6 - 6 ) + 35

= 35 x 0 + 35

= 0 + 35

= 35

Answer 2

35 x 6 - 70 x 3 + 35 

= 35 x 6 - 35 x 2 x 3 + 35 x 1

= 35 x 6 - 35 x 6 + 35 x 1

= 35 x ( 6 - 6 + 1 )

= 35 x 1 

= 35

Answer 3

35 x 6 - 70 x 3 + 35

= 35 x 6 - 35 x 6 + 35

= 35 x ( 6 - 6 + 1 )

= 35 x 1

= 35

Answer 4

35 x 6 - 70 x 3 + 35 = 35 x 6 - 35 x 2 x 3 + 35 x 1

                                = 35 x 6 - 35 x 6 + 35 x 1 

                                = 35 x ( 6 - 6 + 1 )

                                = 35 x 1

                                = 35

Answer 5

35*6-70*3+35

=210-210+35

=0+35

=35

Answer 6

=  35 x 6 - 35 x 6 + 35 + 1

=  35 x ( 6 - 6 + 1 )

=  35      x         1

=            35

Answer 7

35x6-70x3+35

=35x6-35x6+35

=35(6-6+1)

=35x1

=35

Answer 8

          35 x 6 - 70 x 3 + 35

       =35 x 6 -35 x 2 x3 +35 x 1

       =35 x (6- 6 +1)

       =35 x1

       =35

       

Answer 9

35 x 6 -70 x 3 +35

=35 x 6 - 35 x 6 +35

=35 x (6-6+1)

=35 x 1+=35

Answer 10

35 x 6 - 70 x 3 + 35

= 35 x 6 - 35 x 6 + 35

= 35 x ( 6 - 6 + 1 )

= 35 x 1

= 35
