( 100 + 42 ) x 42 + ( 200 - 58 ) x 58
= 142 x 42 + 142 x 58
= 142 x ( 42 + 58 )
= 142 x 100
= 14200
( 100 + 42 ) . 42 + ( 200 - 58 ) . 58
= 142 . 42 + 142 . 58
= 142 . ( 42 + 58 )
= 142 . 100
= 14200
(100 + 42) x 42 + (200 - 58) x 58
= 142 x 42 + 142 x 58
= 142 x (42 + 58)
= 142 x 100
= 14200
\(\left(100+42\right)\cdot42+\left(200-58\right)\cdot58\)
\(=142\cdot42+142\cdot58\)
\(=142\cdot\left(42+58\right)\)
\(=142\cdot100\)
\(=14200\)
[100+42]*42+[200-58]*58
=142*42+142*58
=142*[42+58]
=142*100
=14200
