Understanding (-3)²
In mathematics, the expression (-3)² represents the square of -3. This means we multiply -3 by itself.
Here's how to solve it:
(-3)² = (-3) * (-3) = 9
Key Points to Remember:
- Parentheses are crucial: The parentheses in (-3)² indicate that the entire -3 is being squared, not just the 3.
- Negative times negative is positive: When you multiply two negative numbers, the result is positive.
Therefore, (-3)² equals 9.
