Jerry had 45 action figures on a shelf in his room. Later he added 42 more action figures to the shelf and removed some of the old ones. If there are 32 action figures on his shelf now How many action figures did he remove from the shelf?
Jerry had 45 action figures on a shelf in his room. 

This is our starting point. We are given that Jerry had 45 action figures on his shelf. 

Later he added 42 more action figures to the shelf and removed some of the old ones. 

We are then told that Jerry added 42 more action figures to his shelf, and that he removed some of the old ones. This means that the number of action figures on Jerry's shelf increased by 42. 

If there are 32 action figures on his shelf now

We are told that there are 32 action figures on Jerry's shelf now. This means that the number of action figures on Jerry's shelf decreased by 13. 

How many action figures did he remove from the shelf?

We are asked to find out how many action figures Jerry removed from his shelf. We can do this by finding the difference between the number of action figures on Jerry's shelf at the beginning (45) and the number of action figures on Jerry's shelf at the end (32). This difference is 13, so Jerry removed 13 action figures from his shelf.
