\( \leftarrow \begin{array}{l}\text { Perform the indicated operations. } \\ (11-13)(4-6) \\ (11-13)(4-6)=\square\end{array} \)

First, let's break it down! To solve \( (11-13)(4-6) \), start with the operations inside the parentheses. Calculate \( 11-13 = -2 \) and \( 4-6 = -2 \). Now substitute those values back into the expression: \( (-2)(-2) \). When you multiply two negative numbers, the result is positive. So, \( (-2)(-2) = 4 \). Thus, \( (11-13)(4-6) = 4 \) or \(\square = 4\).
