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.
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.
It is impossible to list the infinite number of composite odd numbers.
would it will be 15
