3.6x42.3x3.75-12.5x0.423x28
=42.3x(3.6x3.75-12.5x0.28)
=42.3x(4x3.75x0.9-12.5x4x0.07)
=42.3x(15-3.5)
=42.3x11.5
=42.3x(10+1.5)
=423+42.3x1.5
=423+42.3x(1+0.5)
=423+42.3+21.15
=465.3+21.15
=486.45
=42.3x(3.6x3.75-12.5x0.28)
=42.3x(4x3.75x0.9-12.5x4x0.07)
=42.3x(15-3.5)
=42.3x11.5
=42.3x(10+1.5)
=423+42.3x1.5
=423+42.3x(1+0.5)
=423+42.3+21.15
=465.3+21.15
=486.45
