    75*10 = 750
    8*4 = 32



    750 - 32 - 2 = 716


    Another easy one, or i got lucky ?

    Anyway, the first few were really tough ... I suppose it's too tempting to look at the next post for the answer :D

    Can't get 474, closest I can get is 476 ... anyway nice way of doing mine , I had :


    75*(3+1) = 300
    300 +9 = 309
    6-4 = 2

    309*2= 618

    94? It needs to be between 100-1000.
