when w=10
w+%287+%283%2F4%29+%2B+1+%282%2F5%29%29+-+2%2F5
=10%2831%2F4+%2B+7%2F5%29+-+2%2F5
=10%28%2831%2A5%29%2F%284%2A5%29+%2B+%287%2A4%29%2F%285%2A4%29%29+-+2%2F5
=10%28155%2F20+%2B+28%2F20%29+-+2%2F5
=10%28183%2F20%29+-+2%2F5
=cross%2810%29%28183%2Fcross%2820%292%29
=183%2F2+-+2%2F5
=91.5-0.4
=91.1
