Concept Check \( \begin{array}{l}\text { 7. There are } 29 \text { students in Ray's class. Each } \\ \text { student has a math book, and each math book } \\ \text { contains } 436 \text { pages. Ray solves the problem } \\ \text { shown to find the total number of pages in the } \\ \text { math books. }\end{array} \)

We start by finding the total number of pages by multiplying the number of students by the number of pages in each book: 1. Each student has one math book. 2. There are \(29\) students. 3. Each math book has \(436\) pages. Thus, the total number of pages is \[ 29 \times 436. \] To calculate: \[ 29 \times 436 = (30 \times 436) - (1 \times 436). \] First, calculate \(30 \times 436\): \[ 30 \times 436 = 13080. \] Next, subtract \(436\): \[ 13080 - 436 = 12644. \] Therefore, the total number of pages in the math books is \[ \boxed{12644}. \]
