Բացատրություն
Here the minus sign stands outside the brackets, so it waits until five has been multiplied by itself and then reverses that twenty-five, landing twenty-five below zero. A sign written inside the brackets would instead be one of the factors, which is why moving the minus sign inside the brackets changes the value.
