    1. N = {1, 2, 3. .. } these are just the counting numbers

    2. multiplication is a basic arithmetic operation

    for natural numbers m, and n, multiplication of m and n is the repeated sum of the other number

    mn = n + .. + n (m times)

    equivalently,

    mn = m + .. + m (n times)

    3. subtraction is ...
