Think of it this way:
3600 divided by 2 is 1800
and 6 divided by 2 is 3.
Since both the dividend and the divisor were divided by 2, the quotient is the same for both because the ratios were the same.
<u>
</u><u>3600</u> = <u>1800
</u> 6 3
cross multiply
10,800=10,800
The quotients are the same (600).

This is false. If we assumed the prime numbers were closed under subtraction, then the difference of any two primes would also get us a prime number.
Take the prime numbers 11 and 7. Their difference, 11 - 7, is 4, but 4 is composite, as it has 2 as a factor other than 1 and 4. All we need is this one counterexample to prove that prime numbers are <em>not </em>closed under subtraction.
