There are (49)5 • 40 books at the library. What is the total number of books at the library? (4 points)
2 answers:
It looks here that you have a normal math problem; the (49)5 parentheses just mean multiply. 49*5=245. Once that's done, multiply 245*40, and you get 9800. Thus, there are 9,800 books in the library.
5 times 40 times 49 equals 9800 because you do 5 time 4 and that's 20 and you add a 0 and you multiply by 49 to get 9800 .
