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!
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.
The only prime number less than 3 is 2.
Composite A prime number is a number that has only two factors (itself and one) A composite number is a number that has more than two factors.
79 isn't a composite number because its only factors are 1 and itself.
