the number of true arithmetical statements involving positive integers, +, x,(,) and = is countable, i.e. "(17+31) x 2 = 96". (True or False)

Answers

Answer 1

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.
