    Family quiz time.

    I need to make 773 from the numbers:

    75
    2
    8
    4
    10
    10

    Using normal countdown rules (only plus minus multiplication and division, no negative numbers or fractions)

    I can do it using 4! but factorial is not within the rules.

    Help!

    ((10 * 8 + 75) * 10 – 4) / 2 = 773

    Closest I can get is 772

    Edit – and there you go up there ^

    10*8=80
    80+75=155
    155*10=1550
    1550-4=1546
    1546/2 = 773
