    3m40cm + 4m24cm – 5m69cm = 195cm
    72m6cm – 56m50cm + 7m44cm = 2300cm
    8m27dm + 3m35cm + 3dm65 cm = 1500cm
    98m20cm * 2 + 23m30cm * 2 = 24300cm
    18m40cm * 4+80m5dm * 8= 71760cm

    3m40cm + 4m24cm – 5m69cm
    = 340 cm + 424 cm – 569 cm
    = 195 cm
    72m6cm – 56m50cm + 7m44cm
    = 7206 cm – 5650 cm + 744 cm
    = 2300 cm
    8m27dm + 3m35cm + 3dm65cm
    = 1070 cm + 335 cm + 95 cm
    = 1500 cm
    98m20cm × 2 + 23m30cm × 2
    = 2 × (9820 cm + 2330 cm)
    = 2 × 12150 cm
    = 24300 cm
    18m40cm × 4 + 80m5dm × 8
    = 1840 cm × 4 + 8050 cm × 8
    = 7360 cm + 64400 cm
    = 71760 cm
