    Step-by-step explanation:

    Assuming that the 350 taking history and the 300 taking math each includes the 270 taking both history and math, then:

    N (H or M) = N (H) + N (M) - N (H and M)

    N = 350 + 300 - 270

    N = 380

    There are 380 first-year students taking history or mathematics.
