Carl and Bob just love apples. Sadly, a stray apple-obsessed chicken broke into their supply and left them with only 248,573 apples! If they had 574,820 apples to start, what is the difference between the two amounts of apples?

248,573 + a = 547,820
574,820-248,573=a
The difference between the two amounts is 326,247 apples.

Carl and Bob love apples more than anybody you know. However, they sadly had an accident at their apple storing barn–a strange chicken-raccoon hybrid broke in and ate many of their apples! Now, they only have 459,968 apples left. If they had 2,072,650 apples to begin with, how many apples did they lose?
2,072,650 - a = 459,968
459,968 + a = 2,072,650
2,072,650 - 459,968 = a
They lost 1,612,682 apples!
