Hank got 22 Pokemon cards from his brother. Then, he got 34 from his friend. Since he's so nice, Hank shared 12 cards with his cousin. How many Pokemon cards does Hank now have?

Answer explanation

First, add the two amounts Hank got. 22 + 34 = 56. Then, subtract the amount he gave to his cousin from the total number he had. 56 - 12 = 44.

For Halloween, Lexy got two bags of candy. The first bag had 537 pieces of candy and the second bag had 496 pieces of candy. On Halloween, kids took 670 pieces. How many pieces of candy does Lexy still have left?

• 330 pieces of candy

• 363 pieces of candy

• 1,033 pieces of candy

• 41 pieces of candy

Answer explanation

Lexy started out with the number of pieces in both bags, so we add those pieces of candy.

537 + 496 = 1,033

Then, kids took some candy, so we need to subtract that number from the total amount of candy Lexy had when Halloween started.

1,033 - 670 = 363 pieces of candy left.

798,064 - 789,456

Answer explanation

Remember, if it's bigger on the bottom, then you need to borrow.
