Explanation :

The number of chapters left is 3, and each chapter has 12 pages. So, the number of pages left to read is (3 × 12).

The book has 342 pages in all. The number of pages Reagan has read is the difference of 342 and (3 × 12):

342 − (3 × 12) = 342 − 36 = 306.

The expression 342 + (-12) + (-12) + (-12) is also equivalent to 306.
