Methods to find quadruple -0.2

Finding the quadruple of -0.2 involves understanding that quadrupling means taking four times the original number. If you start with the value -0.2, you multiply it by 4 to get a new number that is four times as large. In practice, you take the number -0.2 and multiply it by 4, which is written as (-0.2 * 4). This calculation yields -0.8, the quadruple of -0.2. This method works for any number and is a basic operation used frequently in mathematics to scale values by a factor of four.
