Question

64x23+37x23-23

Answer 1

\(64x23+37x23-23\)

\(=23x\left(64+37-1\right)\)

\(=23x100\)

\(=2300\)

Answer 2

   64 x 23 + 37 x 23 - 23

= 64 x 23 + 37 x 23 - 23 x 1

= ( 64 + 37 - 1 ) x 23

= 100 x 23

= 2300

Answer 3

64x23+37x23-23 

= 64x23+37x23-23x1 

= 23 x ( 64 + 37 - 1 ) 

= 23 x 100

=2300

Answer 4

23*(64+37-1)=23*100=2300
