A hardware factory that manufactured screws for one entire week.
Every day there were 300 screws manufactured.
On the second day, 14 screws were defective and and had to be thrown away.
Similarly, on the fourth day 7 screws were thrown away, and on the fifth day 26 screws were thrown away.
How many good screws were manufactured that week?
First, we calculate how many screws the factory produces in total in 7 days:
Now we subtract the number of defective screws that we know the factory discarded on the second day:
Now let's count the number of defective screws that we know the factory discarded on the fourth day:
Now we record the number of defective screws that we know the factory discarded on the fifth day:
