Students can practice their arithmetic skills by solving these eight real-world addition and subtraction scenarios.

Let’s solve each of the 8 word problems step by step, explaining the reasoning behind each solution.

Problem 1.
*The city aquarium has 245 gold fish and 123 rainbow fish. How many fish are there in the aquarium?*

✔ Solution:
We need to find the total number of fish. That means we add the two groups together.

> 245 + 123 = 368

Answer: 368 fish

Problem 2.
*The bike shop orders 275 bikes to sell. The first week they sell 125 bikes. How many bikes do they have left to sell?*

✔ Solution:
They started with 275 and sold 125. To find how many are left, we subtract.

> 275 - 125 = 150

Answer: 150 bikes left to sell

Problem 3.
*Raquel puts 128 crayons in a blue box and 112 crayons in a red box. What is the total number of crayons that Raquel has?*

✔ Solution:
Again, we’re finding the total, so we add the two amounts.

> 128 + 112 = 240

Answer: 240 crayons

Problem 4.
*Harmony has 64 cookies. Her mom gives her 32 more. How many cookies does she have in all? What is the sum? What is the total?*

✔ Solution:
All three phrases — “in all,” “sum,” and “total” — mean the same thing here: add the numbers.

> 64 + 32 = 96

Answer: 96 cookies

*(Note: The question repeats the same idea three times — it’s testing understanding of synonyms for addition.)*

Problem 5.
*Genesis has 527 berries. Her friend has 241. How many more berries does Genesis have than her friend?*

✔ Solution:
To find “how many more,” we subtract the smaller number from the larger one.

> 527 - 241 = 286

Answer: 286 more berries

Problem 6.
*Gavin collected 527 shells. Xian collected 241 shells. About how many more shells does Gavin have than Xian?*

✔ Solution:
This says “About how many more,” which suggests we should estimate.

Let’s round each number to the nearest hundred:

- 527 → 500
- 241 → 200

Now subtract:

> 500 - 200 = 300

*(You could also round to tens: 530 - 240 = 290, which is close to 300.)*

Since it asks for “about,” 300 is a good estimate.

Answer: About 300 more shells

Problem 7.
*Kevin collected a total of 83 golden rocks and silver coins. If 52 of his collection has golden rocks, how many of his collection has silver coins?*

✔ Solution:
Total = golden rocks + silver coins
We know total = 83, golden rocks = 52 → so silver coins = total - golden rocks

> 83 - 52 = 31

Answer: 31 silver coins

Problem 8.
*Isabella is making bracelets. She has 438 red beads and 243 yellow beads. About how many more red beads than blue beads does she have?*

⚠️ Important Note:
There’s a mistake in the problem! It says “red beads and yellow beads,” but then asks “how many more red beads than blue beads.”

She doesn’t have any blue beads mentioned. This is likely a typo.

✔ Most reasonable assumption:
It probably meant to ask: *“How many more red beads than yellow beads does she have?”*

So we’ll solve it that way (assuming “blue” was a mistake for “yellow”).

> 438 - 243 = 195

And since it says “About how many more,” we can estimate:

Round 438 → 440
Round 243 → 240
> 440 - 240 = 200

Answer: About 200 more red beads than yellow beads

*(If we must take “blue beads” literally — and she has 0 blue beads — then answer would be 438. But that doesn’t make sense contextually. So correction to “yellow” is logical.)*

2. 150 bikes
3. 240 crayons
4. 96 cookies
5. 286 more berries
6. About 300 more shells
7. 31 silver coins
