Finding the double of -3.5

To find the double of -3.5, you start by taking the given number represented by -3.5. 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 -3.5 by 2. The expression (-3.5 * 2) captures this operation mathematically. When you multiply -3.5 by 2, the product you get, denoted as -7, is exactly double the original number. For example, if -3.5 were 7, then -7 would be (7 * 2), which is 14. This logic applies universally to any real number represented by -3.5, making -7 the doubled value of -3.5.
