I a wondering if zero is an integer in mathematical purposes
0 is an integer number in math, where integer numbers are the infinite set: .
Depending on circumstances, the "natural numbers" and "natural numbers with zero" are also sometimes referred to as integers, quietly dropping the "positive" or "non-negative" property of the set.
Note, the former does *not* include 0.
Fermat's Last Theorem states that
xn + yn = zn
has no non-zero integer solutions for x, y and z when n > 2.
In number theory, Fermat's Last Theorem states that no three positive integers a, b, and c can satisfy the equation an + bn = cn for any integer value of n greater than two.
