    Nathan's estimate would be greater than the actual product.

    Step-by-step explanation:

    Let a, b, c, d be natural numbers such that a
    Multiplying a positive number on both sides doesn't affect the inequality

    ⇒a*b < c*b and c*b < c*d

    ⇒a*b < c*d

    Here 67<70 and 36<40

    ∴67*36<70*40

    Hence, Nathan's estimate would be greater than the actual product.
