The only 2-digit odd composite number less than 20 is 15. A composite number is a positive integer greater than 1 that has more than two distinct positive divisors. In the case of 15, it can be factored into 3 and 5, making it composite.

Oh, what a happy little question! The only 2-digit odd composite number less than 20 is 15. It's made up of smaller numbers like 3 and 5, creating a beautiful composition of mathematics. Just remember, every number is special in its own way!

What number is it when the the ones digit is one more than its tens digit and it's a composite number has two digits and it's even and has two less than a square number?

Let's list the requirements for the mystery number: One's digit more than the ten's digit. Composite number. Two digits. Even number. Is two less than a square. Now that we've listed the requirements, let's look for a place to "attack" the problem. The easiest is probably to look at squares since our mystery number is two less than a square. Here are the first few squares: 1, 4, 9, 16, 25, 36, 49, 64, 81, 100 and 121. Since our mystery number is 2 less than a square, let's go through that. -1, 2, 7, 23, 34, 47, 62, 79, 98, 119. Now we'll look at two things at once; we'll look only at the 2-digit numbers that are even. (We don't have to look at the "composite number issue" because every even number except 2 is composite since it can be divided by 2.) 34, 62, and 98. Now the number with the one's digit greater than the ten's digit - and there's only one of them: 34. The number 34 has a one's digit greater than the ten's digit, is composite, has two digits, is even, and is 2 less than a square.
