It is a word problem that requires you to do two different calculations (like addition and then subtraction, or two additions) to find the final answer.
There are \(15\) children on the bus. At the first stop, \(5\) more get on. At the second stop, \(3\) get off. How many children are on the bus now?
Step 1 (add): \(15 + 5 = 20\) children after the first stop. Step 2 (subtract): \(20 - 3 = 17\) children. There are \(17\) children on the bus.
You have \(20\) stickers. You give \(6\) to your friend and then buy a new pack of \(10\). How many stickers do you have now?
Step 1 (subtract): \(20 - 6 = 14\) stickers left. Step 2 (add): \(14 + 10 = 24\) stickers. You now have \(24\) stickers.
A pet store had \(12\) puppies. They sold \(4\) puppies. Then, a new litter of \(7\) puppies was born. How many puppies does the store have now?

Lisa started with \(50\) beads. She used \(15\) for a bracelet and \(20\) for a necklace. How many beads does she have left?
Method 1: First add the beads used (\(15 + 20 = 35\)), then subtract from the start (\(50 - 35 = 15\)). Method 2: Subtract in two steps (\(50 - 15 = 35\), then \(35 - 20 = 15\)). She has \(15\) beads left.
Mark had \(18\) cookies. He ate \(3\) cookies. His mom then gave him \(6\) more. How many cookies does Mark have now?
Step 1 (subtract): \(18 - 3 = 15\) cookies. Step 2 (add): \(15 + 6 = 21\) cookies. Mark has \(21\) cookies now.
There are \(28\) students in class. \(12\) are boys. Today, \(3\) girls are absent. How many girls are in class today?
Step 1 (find total girls): \(28 - 12 = 16\) girls in the class. Step 2 (subtract absent girls): \(16 - 3 = 13\) girls. There are \(13\) girls in class today.
Sam wants a toy that costs \($30\). He has \($14\) from his allowance and his grandma gave him \($10\). How much more money does he need?
Step 1 (find total money he has): \($14 + $10 = $24\). Step 2 (find money needed): \($30 - $24 = $6\). He needs \($6\) more.
At the park, there were \(25\) kids. \(10\) kids were playing soccer and \(8\) were on the swings. The rest were on the slide. How many kids were on the slide?
Step 1 (find kids who are busy): \(10 + 8 = 18\) kids. Step 2 (find kids on slide): \(25 - 18 = 7\) kids. There were \(7\) kids on the slide.
A farmer has \(45\) chickens. He sells \(15\) of them. He then buys \(20\) more. How many chickens does the farmer have in the end?
Jenny had \(100\) stamps. She gave \(25\) to her brother. She then received \(40\) new stamps for her birthday. How many stamps does she have now?
Step 1 (give away stamps): \(100 - 25 = 75\) stamps. Step 2 (receive new stamps): \(75 + 40 = 115\) stamps. Jenny now has \(115\) stamps.
A library has \(250\) books. On Monday, \(40\) books were checked out. On Tuesday, \(60\) more books were checked out. How many books are left in the library?
Method 1: Add the books checked out (\(40 + 60 = 100\)), then subtract from the total (\(250 - 100 = 150\)). Method 2: Subtract in two steps (\(250 - 40 = 210\), then \(210 - 60 = 150\)). There are \(150\) books left.
