Miss Darlington has a basket of 20 blueberries. She picked 9 more baskets with the same amount of berries. How many blueberries did Miss Darlington have in all?
Miss Darlington picked 9 x 20 = <T>multiply(9, 20)=180 blueberries more.
So she had a total of 180 + 20 = <T>add(180, 20)=200 blueberries.
