Problem: A pirate buried a treasure of gold coins in an island. He buried 'd' gold coins and then buried 5 more coins the next day. If the total number of buried coins is 10, how many coins did the pirate bury the first day?

Claude-3 Haiku:

Okay, let's break this down step-by-step:
* The pirate buried 'd' gold coins on the first day
* The next day, he buried 5 more coins
* The total number of buried coins is 10

We can set up an equation to solve for 'd':
* Total coins = d + (d + 5)
* 10 = 2d + 5
* 5 = 2d
* d = 2.5

However, since we cannot have a fractional number of coins, the number of coins buried on the first day must be an integer.

Therefore, the number of coins the pirate buried on the first day is 2.

Problem: A toothpaste brand packs 10 tubes of toothpaste into each box. If a store receives 14 tubes of toothpaste, how many did not come from a full box?

Claude-3 Haiku:

Okay, let's break this down step-by-step:
* The toothpaste brand packs 10 tubes of toothpaste into each box.
* The store received 14 tubes of toothpaste.

To find how many tubes did not come from a full box, we need to determine how many full boxes were received, and then subtract that from the total number of tubes received.

First, let's find how many full boxes were received:
* 14 tubes / 10 tubes per box = 1.4 boxes
* Since we can't have a partial box, we round down to 1 full box.

Now, we can subtract the number of tubes from the full box to find how many did not come from a full box:
* 1 full box x 10 tubes per box = 10 tubes
* 14 tubes received - 10 tubes from the full box = 4 tubes that did not come from a full box.

Problem: John has a total of 12 beach balls. He just purchased 10 more to add to his collection. How many beach balls did he have originally?

Claude-3 Haiku:

Okay, let's break this down step-by-step:
* John originally had a total of 12 beach balls
* He then purchased 10 more to add to his collection
* So the total number of beach balls he has now is 12 + 10 = 22

To find out how many beach balls he had originally, we can subtract the number of new beach balls he purchased (10) from the total number of beach balls he has now (22).

Problem: Eli has 10 toy cars in the sandbox. If he found a total of 11 toy cars in there, how many toy cars had been buried in the sandbox that he did not initially see?

Claude-3 Haiku:

Okay, let's break this down step-by-step:
* Eli initially had 10 toy cars in the sandbox
* He then found a total of 11 toy cars in the sandbox
* This means that there were additional toy cars that he did not initially see

To find the number of toy cars that were buried in the sandbox that he did not initially see, we can subtract the number of cars he initially had from the total number of cars he found:
* Total cars found - Initial cars = Cars not initially seen
* 11 - 10 = 1

Therefore, Eli found 1 additional toy car that had been buried in the sandbox that he did not initially see.
