What is happening in this word problem? In this problem, our farmer has planted some number of orange trees and also some number of mango trees. If we want to know the total number of trees he planted, we’ll need to add the number of orange trees plus the number of mango trees.
There were 200 orange trees plus 300 mango trees. If we add two hundreds plus three hundreds together, we will have five hundreds. Another way to write five hundreds is five zero zero. The farmer planted a total of 500 trees.
