Finding the double of -10

To find the double of -10, you start by taking the given number represented by -10. 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 -10 by 2. The expression (-10 * 2) captures this operation mathematically. When you multiply -10 by 2, the product you get, denoted as -20, is exactly double the original number. For example, if -10 were 7, then -20 would be (7 * 2), which is 14. This logic applies universally to any real number represented by -10, making -20 the doubled value of -10.
