    ten choices for president times 9 choices for vp times 8 choices for treasurer times 7 choices for secretary = \[10\times 9\times 8\times 7\]

    it is P(10,4) not P(10,3) as you have 4 positions to fill, not 3!

    write the problem in P(n,r) notation then use counting permutation formula to get the numerical answer..
