Finding the double of 15

To find the double of 15, you start by taking the given number represented by 15. Doubling means you want to find a number twice as big, so the natural operation to perform is multiplication by 2. This is why the calculation involves multiplying 15 by 2. The expression (15 * 2) captures this operation mathematically. When you multiply 15 by 2, the product you get, denoted as 30, is exactly double the original number. For example, if 15 were 7, then 30 would be (7 * 2), which is 14. This logic applies universally to any real number represented by 15, making 30 the doubled value of 15.
