Problem 1:

There were 46 balls on the playground. 20 were soccer balls and 15 were basketballs. The rest were tennis balls. How many were tennis balls?

Step-by-step solution:
- Total balls = 46
- Soccer balls = 20
- Basketball = 15
- Tennis balls = ?

To find the number of tennis balls, subtract the number of soccer and basketballs from the total:

$$
\text{Tennis balls} = 46 - 20 - 15 = 11
$$

✔ Answer: 11 tennis balls

Problem 2:

30 children lined up to jump rope. 9 children joined them. 4 children left to get a drink of water. How many children were left in the line?

Step-by-step solution:

Problem 3:

Dad caught 22 fish in the morning. He threw 5 back because they were too small. He caught 12 more in the afternoon. How many fish did dad have then?

Step-by-step solution:
- Morning catch = 22
- Threw back 5 → $22 - 5 = 17$ (remaining)
- Afternoon catch = 12
- Total fish = $17 + 12 = 29$

✔ Answer: Dad had 29 fish

Problem 4:

At the park I saw 32 animals. I saw 12 dogs, 15 squirrels, and some frogs. How many frogs did I see?

Step-by-step solution:

- Dogs = 12
- Squirrels = 15
- Frogs = ?

Add dogs and squirrels:
$$
12 + 15 = 27
$$
Subtract from total:
$$
32 - 27 = 5
$$

✔ Answer: 5 frogs
