The statement is true because the set of all possible arithmetical statements involving positive integers, +, x, (, ), and = is equivalent to the set of all possible strings of symbols over a finite alphabet, which is countable.
To see why this is the case, we can consider a bijection between the set of all possible arithmetical statements and the set of all possible finite strings of symbols. For example, we can map the arithmetical statement "3 + 4 = 7" to the string "3+4=7", and map the statement "(5 x 2) + 1 = 11" to the string "(5x2)+1=11".
Since the set of all possible finite strings of symbols over a finite alphabet is countable (for example, by constructing a one-to-one correspondence with the set of all possible binary sequences), the set of all possible arithmetical statements is also countable.

In a typical office, biometric authentication might be used to control access to employees and registered visitors only. We know the system will have some false negatives, some employees falsely denied access, so we need a human override, someone who can examine the employee and allow access in spite of the failed authentication.
