Finding the double of 45

To find the double of 45, you start by taking the given number represented by 45. 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 45 by 2. The expression (45 * 2) captures this operation mathematically. When you multiply 45 by 2, the product you get, denoted as 90, is exactly double the original number. For example, if 45 were 7, then 90 would be (7 * 2), which is 14. This logic applies universally to any real number represented by 45, making 90 the doubled value of 45.
