What does composite means in math?
A composite number is a number that has more than 2 whole number "factors".Factors are numbers that multiply other numbers to get another number.Example:2 * 5 = 101 * 10 = 101, 2, 5, 10 are all factors of 10. Since 10 has four factors, which is greater than 2, it is a composite number!Prime numbers have exactly 2 factors.You can only multiply 1 and 7 to get 7. 7 is prime.1 is neither prime nor composite.
