Paul had

80

fliers to post around town. Last week, he posted

14

of them. This week, he posted

25

of the remaining fliers. How many fliers has he still not posted?

To find how many filers he still hadn't posted yet, all you've got to do is add the number of fliers he did put up in the two weeks and subtract them from 80 to get how many fliers he has left to put up.

80-14

Subtract

66-25

Subtract again

Final Answer: 41

This means that he still has 41 fliers that he still hadn't posted.
