\[ \text{Find } 2011^2 - 2010^2 \text{?} \]

To solve the expression \( 2011^2 - 2010^2 \), we can use the difference of squares formula, which states that \( a^2 - b^2 = (a-b)(a+b) \). Here, we can let \( a = 2011 \) and \( b = 2010 \). Calculating the values gives us: \[ a - b = 2011 - 2010 = 1 \] \[ a + b = 2011 + 2010 = 4021 \] Now substituting these values into the formula: \[ 2011^2 - 2010^2 = (1)(4021) = 4021 \] Thus, the solution to \( 2011^2 - 2010^2 \) is \( \boxed{4021} \).
