Yes, when you square a negative number, it becomes positive. This is because squaring a number means multiplying it by itself. For example, if we take the negative number -3 and square it, we calculate:
-3 × -3 = 9
In this operation, we have two negative signs multiplied together, and the rule in mathematics states that multiplying two negative numbers results in a positive number. Therefore, the square of -3 is indeed 9, which is positive.
