Finding the double of 42

To find the double of 42, you start by taking the given number represented by 42. 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 42 by 2. The expression (42 * 2) captures this operation mathematically. When you multiply 42 by 2, the product you get, denoted as 84, is exactly double the original number. For example, if 42 were 7, then 84 would be (7 * 2), which is 14. This logic applies universally to any real number represented by 42, making 84 the doubled value of 42.
