Finding the double of 40

To find the double of 40, you start by taking the given number represented by 40. 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 40 by 2. The expression (40 * 2) captures this operation mathematically. When you multiply 40 by 2, the product you get, denoted as 80, is exactly double the original number. For example, if 40 were 7, then 80 would be (7 * 2), which is 14. This logic applies universally to any real number represented by 40, making 80 the doubled value of 40.
