19.6*4.8-6.4*4.8+2.7*4.8
=4.8*(19.6-6.4+2.7)
=4.8*15.9
=5*15.9-0.2*15.9
=79.5-3.18
=76.32
=4.8*(19.6-6.4+2.7)
=4.8*15.9
=5*15.9-0.2*15.9
=79.5-3.18

19.6╳4.8-6.4╳4.8+5.4╳2.4
=4.8x(19.6-6.4)+5.4x2.4
=4.8x13.2+2.7x2x2.4
=4.8x(13.2+2.7)
=4.8x15.9
=4.8x16-4.8x0.1
=5x16-0.2x16-0.48
=80-3.2-0.48
=80-3.68
=76.32
=4.8x(19.6-6.4)+5.4x2.4
=4.8x13.2+2.7x2x2.4
=4.8x(13.2+2.7)
=4.8x15.9
=4.8x16-4.8x0.1
=5x16-0.2x16-0.48
=80-3.2-0.48
