Prime numbers are closed under subtraction

Mathematics
1 answer:
Alona [7]3 years ago
6 0

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.

HELP ME OUT peps correct answers only
Elena L [17]

Based on the subtraction property of equality: C. Correct. Jen could have also subtracted 100 from both sides and then divide both sides by -1/2.

<h3>What is the Subtraction Property of Equality?</h3>

In order to balance both sides of an equation, we can subtract same value from both sides by subtracting a value from both sides based on the subtraction property of equality. Same applies to other operations.

To balance both sides of the equation, 100 needs to be subtracted from the equation given. This means Jen was correct.

If she also divide both sides by -1/2, she would get same result as when she multiplies both sides by -2.

The correct description of the accuracy of her work is: C. Correct. Jen could have also subtracted 100 from both sides and then divide both sides by -1/2.
