Problem: Gene has 5 beach towels, but his younger brother takes 2 of them to the neighborhood swimming pool. Later on, his mom gives him an extra 2 towels. How many towels does Gene have now?

Gemma 2B:

  Gene has 5 beach towels.
His younger brother takes 2 of them to the neighborhood swimming pool, so Gene has 5 - 2 = <<5-2=3>>3 towels left.
Later, his mom gives him an extra 2 towels, so Gene has 3 + 2 = <<3+2=5>>5 towels now.

Problem: James has 2 helicopters from his birthday party and buys 1 more from the toy store. Rebecca had 4 helicopters, but she gave James the same number of helicopters that he already had. How many helicopters does Rebecca now have?

Gemma 2B:

  Let's start by using the information that James has 2 helicopters from his birthday party and buys 1 more from the toy store. This means that James has a total of 2 + 1 = 3 helicopters.

Now, let's look at what happens to Rebecca's helicopters. We know that Rebecca had 4 helicopters, but she gave James the same number of helicopters that he already had. This means that Rebecca gave James 2 helicopters, since James already had 2 helicopters from his birthday party.

So, Rebecca now has 4 - 2 = 2 helicopters left.

Therefore, the final answer is:

### Answer: 2

Expected answer: 1

🔗 Problem

Problem: There were 2 dragons playing in the field, but then 1 of them decided to leave and go back to its lair. Later, 4 other dragons saw the single dragon playing in the field and wanted to join it, but they realized they needed to leave the dragons in their lair by subtracting the number of dragons already playing in the field. How many dragons had to leave their lair to join the playing dragon?

Gemma 2B:

  There were 2 dragons playing in the field initially.
When 1 dragon left, there was only 1 dragon left playing in the field.
When 4 other dragons saw the single dragon playing in the field, they wanted to join it.
To find out how many dragons had to leave their lair to join the playing dragon, we need to subtract the number of dragons already playing in the field from the total number of dragons that wanted to join.

Total number of dragons that wanted to join = 4
Number of dragons already playing in the field = 1

Subtracting the number of dragons already playing in the field from the total number of dragons that wanted to join, we get:
4 - 1 = 3

Therefore, 3 dragons had to leave their lair to join the playing dragon.

Expected answer: 3

🔗 Problem

Problem: Trevor had collected 1 seashell in the morning. He found 3 more seashells in the afternoon. However, he lost 3 seashells while playing in the sand. How many seashells does Trevor have now?

Gemma 2B:

  Trevor had 1 seashell in the morning.
He found 3 more seashells in the afternoon, so he had 1 + 3 = 4 seashells.
He lost 3 seashells while playing in the sand, so he had 4 - 3 = 1 seashell left.
Therefore, Trevor has 1 seashell now.

Expected answer: 1

Correct? Yes

🔗 Follow-up

Problem: In the original scenario, Trevor had actually found 3 seashells in the afternoon instead of 1. Taking into account that he still lost 2 seashells while playing, how many seashells does Trevor have now?

Gemma 2B:

  Trevor had 1 seashell in the morning.
He found 3 seashells in the afternoon, so he had 1 + 3 = 4 seashells.
He lost 2 seashells while playing in the sand, so he had 4 - 2 = 2 seashells left.
Therefore, Trevor has 2 seashells now.

Therefore, the wizard has 4 phoenix feathers now.

Expected answer: 4

Correct? Yes

🔗 Follow-up

Problem: The wizard originally had 1 phoenix feather and found 2 more. If he still used 2 feathers to make the potion, as in the first scenario, how many phoenix feathers would he have left?

🔗 Problem

Problem: Jack has 2 monkeys. Susan has as many monkeys as Jack has, plus another 2 monkeys identical to Jack's monkeys. How many monkeys does Susan have?

Gemma 2B:

  Let's start by identifying the information we have:

* Jack has 2 monkeys.
* Susan has as many monkeys as Jack has, plus another 2 monkeys identical to Jack's monkeys.

We can represent this information as follows:

Jack: 2 monkeys
Susan: x monkeys

Since Susan has as many monkeys as Jack has, we can write:

Susan: x = Jack

Now, we know that Susan has 2 more monkeys than Jack, so we can write:

Susan: x = Jack + 2

Substituting the value of Jack's monkeys, we get:

Susan: x = 2 + 2
Susan: x = 4

Therefore, Susan has 4 monkeys.

Problem: In a game of cards, Umer won 5 rounds but lost 4 rounds. Sam, on the other hand, won twice as many rounds as Umer won after subtracting his losses. How many rounds did Sam win?

Gemma 2B:

  Let's start by analyzing the information given in the problem:

* Umer won 5 rounds and lost 4 rounds, so he won 5 - 4 = 1 round more than he lost.
* Sam won twice as many rounds as Umer won after subtracting his losses, so Sam won 2(1) = 2 rounds more than Umer won.

Now, let's find out how many rounds Sam won in total:

Sam won 2 rounds more than Umer won, so Sam won 1 + 2 = 3 rounds more than Umer won.

Therefore, Sam won 3 rounds in total.

🔗 Problem

Problem: There are 3 hinges on a door, but one of them breaks off. Then, another door has 2 hinges and some additional hinges equal to the number left on the first door. How many hinges are there in total on the second door?

Gemma 2B:

  Let's call the number of hinges on the first door "x". Since one of the hinges broke off, there are now x-1 hinges on the first door.

On the second door, there are 2 hinges and some additional hinges equal to the number left on the first door. Let's call the number of additional hinges "y".

So, the total number of hinges on the second door is 2 + y.

We know that y is equal to x-1, so we can substitute this into the equation:

2 + y = 2 + (x-1)

Simplifying, we get:

2 + y = x

Now, we can solve for x by subtracting 2 from both sides:

x - 2 = y

Now, we can solve for y by adding 2 to both sides:

y = x + 2

So, there are x + 2 hinges on the second door.

🔗 Problem

Problem: At a campfire, John gathered 3 medium-sized logs and added 1 large log. Then, from the 5 logs close to the campfire, he used what he gathered. How many logs close to the campfire are left?

Gemma 2B:

  Let's start by identifying the information we have:

* John gathered 3 medium-sized logs and added 1 large log.
* He used what he gathered from the 5 logs close to the campfire.

We can start by assuming that the 5 logs close to the campfire are all the same size. Let's call the size of each log "x".

John gathered 3 logs of size "x" and added 1 log of size "2x" (since the large log is twice as big as the medium-sized logs). So, the total size of the logs he gathered is:

3x + 2x = 5x

Since John used what he gathered from the 5 logs close to the campfire, we can assume that he used all 5 logs. Therefore, the number of logs close to the campfire that are left is:

5x - 5x = 0

So, there are 0 logs close to the campfire that are left.

Problem: Jacob set his analog watch 2 hours ahead before falling asleep. When he woke up, he adjusted it 3 more hours ahead. Later he realized his watch was running too fast, so he set it 4 hours backward. What is the final time difference on his watch from the actual time?

Gemma 2B:

  Let's break this down step by step:

1. Jacob set his watch 2 hours ahead before falling asleep, so the time on his watch was 2 hours ahead of the actual time.
2. When he woke up, he adjusted his watch 3 more hours ahead, so the time on his watch was now 3 hours ahead of the actual time.
3. Later, Jacob realized his watch was running too fast, so he set it 4 hours backward. This means the time on his watch was now 4 hours behind the actual time.

To find the final time difference on Jacob's watch from the actual time, we need to add the time differences from steps 1 and 2, and then subtract the time difference from step 3.

So, the final time difference on Jacob's watch from the actual time is:

2 hours + 3 hours = 5 hours

5 hours - 4 hours = 1 hour

Therefore, the final time difference on Jacob's watch from the actual time is 1 hour.
