A prime number is a number that has only 1 and itself as factors. (only 2 factors) This means, only 1 and that number can evenly divide into the number you're talking about. For example: 7 is prime because the only numbers that divide into 7 are 1 and 7. 10 is NOT prime, because I can divide 1, 2, 5, and 10 into it. it has 4 factors (more than 2) so it is not a prime number. 10 is called a composite number. A number that is not prime is composite.
It is: 10-7 = 3
x/7=10
