Well, friend, 43 is a two-digit odd number because it has two digits and is not divisible by 2. It is a Prime number, not a composite number, because it can only be divided by 1 and itself. Remember, every number is unique and special in its own way, just like you are unique and special too.
No, it is not.
No, it is not.
Yes, 43 is a two-digit odd number because it has two digits and is not divisible by 2. It is a prime number because it can only be divided by 1 and itself. A composite number is a positive integer greater than 1 that has at least one positive divisor other than 1 and itself, so 43 is not a composite number.
Julia is incorrect. 2 is an even prime number and 9 is an odd composite number.
The answer is 'no', so there isn't any 'why'. As a matter of fact, every EVEN number except 2 is composite, and every prime number bigger than 2 is odd..
No, it is not.
42 is composite, 43 is prime.
No, it is not.
No, it is not.
No, it is not.

Incorrect. Square numbers are composite and have an odd number of factors.

23?

Look at the last digit. If the last digit of a number is even, the whole number is even. If the last digit is odd, the number is odd.
