(100 + 42 ).42 + 58(200 - 58)
= 142.42 + 58.142
= 142.(42 + 58)
= 142.100
= 14200
(100+42).42+58.(200-58)
=142.42+58.42
=142.(42+58)
=142.100
=14200
\(\left(100+42\right).42+58\left(200-58\right)\)
\(=142.42+58.142\)
\(=142\left(42+58\right)\)
\(=142.100\)
\(=14200\)
\(\left(100+42\right)\times42+58\times\left(200-58\right)\)
\(=142\times42+58\times142\)
\(=142\times\left(42+58\right)\)
\(=142\times100\)
\(=14200\)
