Ta có: \(13\cdot\left(-37\right)-23\cdot37-46\cdot\left(-37\right)\)

\(=13\cdot\left(-37\right)+23\cdot\left(-37\right)-46\cdot\left(-37\right)\)

\(=\left(-37\right)\cdot\left(13+23-46\right)\)

\(=\left(-37\right)\cdot\left(-10\right)=370\)

=46x ( 37+93)+54 x (61+69)

= 46 x 130 + 54 x 130

=13000

46 x 37 + 93 x 46 + 54 x 61 + 69 x 54

= 46 x ( 37 + 93 ) + 54 x ( 61 + 69 )

= 46 x 120 + 54 x 120

= 120 x ( 46 + 54 )

= 120 x 100
