Calculate 6² - (-6)²: Comparing Positive and Negative Squares

To solve the expression $6^2 - (-6)^2$, let's follow these steps:

• Step 1: Calculate $6^2$.
  $6^2 = 6 \times 6 = 36$.
• Step 2: Calculate $(-6)^2$.
  $(-6)^2 = (-6) \times (-6) = 36$. Note that squaring a negative number results in a positive value.
• Step 3: Subtract the results of Step 1 and Step 2.
  $36 - 36 = 0$.

Therefore, the solution to the problem is $0$.
