Problem: Julia has 10 dollars in her wallet. If she originally had 1 dollar before her mother gave her some more money, how much money did her mother give her?

GPT-4o:

To determine how much money Julia's mother gave her, we need to subtract the amount Julia originally had from the total amount she has now.

Julia originally had 1 dollar. After her mother gave her some money, she now has 10 dollars.

Let's denote the amount of money her mother gave her as \( x \).

The equation to represent this situation is:
\[ 1 + x = 10 \]

To find \( x \), we subtract 1 from both sides of the equation:
\[ x = 10 - 1 \]
\[ x = 9 \]

So, Julia's mother gave her 9 dollars.

Problem: There are 10 craters on the moon. After astronomers spotted 3 new craters, how many craters were there before?

GPT-4o:

To determine the number of craters on the moon before the astronomers spotted the 3 new craters, we need to subtract the number of new craters from the total number of craters after the new ones were spotted.

Given:
- Total number of craters after spotting new ones: 10
- Number of new craters spotted: 3

Let's denote the number of craters before the new ones were spotted as \( x \).

We can set up the equation:
\[ x + 3 = 10 \]

To find \( x \), we subtract 3 from both sides of the equation:
\[ x = 10 - 3 \]
\[ x = 7 \]

So, there were 7 craters before the astronomers spotted the 3 new craters.

Problem: Peter had 10 shirts in his closet. After buying a new shirt, he found out he only had one shirt before the purchase. How many shirts did he buy?

GPT-4o:

Let's break down the problem step by step.

1. Peter initially had 10 shirts in his closet.
2. After buying a new shirt, he found out he only had one shirt before the purchase.

This implies that the initial count of 10 shirts was incorrect. If he had only one shirt before the purchase, then the number of shirts he had after buying the new shirt would be:

\[ 1 \text{ (initial shirts) } + 1 \text{ (new shirt) } = 2 \text{ shirts} \]

However, the problem states that he initially thought he had 10 shirts, but in reality, he had only one shirt before the purchase. This means he bought:

\[ 10 \text{ (initial incorrect count) } - 1 \text{ (actual initial count) } = 9 \text{ shirts} \]

So, Peter must have bought 9 shirts to correct the count from 1 to 10.

To determine the height the dolphin covers with its body strength alone, we need to subtract the distance covered by the tail thrust from the total distance of the jump.

Given:
- Total distance of the jump: 10 feet
- Distance due to tail thrust: 9 feet

We calculate the height covered by the dolphin's body strength alone as follows:
\[ \text{Height covered by body strength} = \text{Total distance} - \text{Distance due to tail thrust} \]
\[ \text{Height covered by body strength} = 10 \text{ feet} - 9 \text{ feet} \]

Problem: There were 10 clouds in the sky on a sun-drenched day. 3 of those clouds were dark and stormy. How many clouds were fluffy and white?

GPT-4o:

To determine the number of fluffy and white clouds, we need to subtract the number of dark and stormy clouds from the total number of clouds.

\[ \text{Number of fluffy and white clouds} = \text{Total number of clouds} - \text{Number of dark and stormy clouds} \]
\[ \text{Number of fluffy and white clouds} = 10 - 3 \]
\[ \text{Number of fluffy and white clouds} = 7 \]
