Question

10x7+10x2+10

Answer 1

10 x 7 + 10 x 2 + 10

=  70   + 20       + 10

=   90                + 10

= 100.

Answer 2

10 x 7 + 10 x 2 + 10

= 10 x ( 7 + 2 + 1)

= 10 x 10

= 100

Answer 3

= 10 * ( 7+2+1 )

= 10 * 10 

= 100

Answer 4

10 x 7 + 10 x 2 + 10 = 10 x (7 + 2 + 1) 

                               = 10 x  10 

                                = 100

Answer 5

10 x 7 + 10 x 2 + 10

= 10 x 7 + 10 x 2 + 10 x 1

= 10 x ( 7 + 2 + 1 )

= 10 x ( 9 + 1 )

= 10 x 10

= 100

Answer 6

      \(10\cdot7+10\cdot2+10\)

\(=10\cdot7+10\cdot2+10\cdot1\)

\(=10\cdot\left(7+2+1\right)\)

\(=10\cdot10\)

\(=100\)

Answer 7

\(10\times7+10\times2+10\)

\(=70+20+10\)

\(=100\)

Answer 8

10x7+10x2+10=10x(7+2+1)

                     =10x10

                     =100

Answer 9

   10 x 7 + 10 x 2 + 10 = 10 x ( 7 + 2 + 1 ) 

                                 = 10 x 10 

                                = 100

Answer 10

10x7+10x2+10=10x7+10x2+10x1=10x(7+2+1)=10x10=100.
