The multiplication is completed first and the minus sign is then applied to the result.✓Correct answer
Only a minus sign written inside the brackets would take part in the multiplication.✓Correct answer
-(5 * 5) and (-5) * (-5) are two ways of writing the same value.
Explanation
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.
