Maya loves to read books. Last week she read 5 books. Each book had 300 pages of text. This week she read twice as much. How many pages did Maya read in total?
Last week Maya read 5 * 300 = <T>multiply(5, 300)=1500 pages of text.
This week she doubled the result, so she read 2 * 1500 = <T>multiply(2, 1500)=3000 pages.
In total Maya read 1500 + 3000 = <T>add(1500, 3000)=4500 pages of text.
