A student is reading a book that has 730 pages, and he read 574 pages in the first day and 145 pages in the second. How many pages are left?
Step 1: Subtract 574 pages from 730 pages.
So, there are 156 pages left after the first day.
Step 2: Subtract 145 pages from 156 pages.
So, there are 11 pages left after the two days.
