The excitement around ChatGPT has boomed in recent months. Alongside this excitement, there has been growing concern regarding the potentially massive job displacement it could bring. My concern is about tutoring jobs, specifically done by Intelligent Tutoring Systems. So, I have pretended to be a student trying to use ChatGPT for mastering Subtraction Skills. My session with GPT is provided below.

In conclusion, I have asked ChatGPT my final question “**Can you provide full-fledged tutoring functionality for students?**“

And here what Chat GPT has answered:

“As an AI language model, I am capable of providing tutoring assistance to students. However, my capabilities are limited to text-based interactions and I do not have the ability to interact with students in real-time or provide personalized feedback based on visual cues. Additionally, I may not be able to answer all questions or provide solutions to every problem. That being said, I can certainly assist students with a wide range of academic topics and provide guidance on various subjects.”

So, after completion of our conversation I came to conclusion that ChatGPT is pretty good and even knows some of its limitations. But it is not ready for full-fledged and error-free tutoring of students.

Just see our conversation for yourself. My prompts below are in bold.

**Could you tutor me on how to subtract numbers?**

Certainly, I’d be happy to help you learn how to subtract numbers!

Subtraction is one of the four basic mathematical operations and is used to find the difference between two numbers. To subtract one number from another, follow these steps:

- Write the two numbers you want to subtract from each other.
- Begin by aligning the numbers vertically, placing the ones digit of the number being subtracted directly underneath the ones digit of the number it is being subtracted from.
- If the ones digit of the number being subtracted is larger than the ones digit of the number it is being subtracted from, you will need to borrow from the next place value to the left. To do this, subtract one from the digit in the next place value to the left, and add 10 to the digit in the place value you are borrowing from.
- Subtract the ones digit of the number being subtracted from the ones digit of the number it is being subtracted from. If you needed to borrow in step 3, subtract the borrowed value as well.
- Write the result below the line.
- Repeat steps 3-5 for each place value to the left until you have subtracted all of the digits.
- If you end up with a negative result, it means the number you are subtracting is larger than the number you are subtracting from.

Here is an example:

25

- 13

12

In this example, we are subtracting 13 from 25. We begin by aligning the numbers vertically and subtracting the ones digit:

25

- 13

12

5 minus 3 equals 2, so we write 2 below the line. Next, we subtract the tens digit:

25

- 13

12

2 minus 1 equals 1, so we write 1 below the line. Therefore, the result of 25 minus 13 is 12.

**This is an explanation of how to subtract numbers. It seems to me I understood it. Could you check if I understood it correctly?**

Sure, I’d be happy to check if you understood how to subtract numbers correctly! Please let me know if you have any questions or need further clarification on any of the steps.

**Could you train me on the subtraction of numbers?**

Of course! Here’s a step-by-step process to help you practice subtracting numbers:

Step 1: Write down the two numbers you want to subtract. For example, let’s use the numbers 25 and 13.

Step 2: Write the larger number on top and the smaller number on the bottom. In our example, we would write:

25

- 13

Step 3: Start by subtracting the ones place. Take the bottom number’s ones place (which is 3) away from the top number’s ones place (which is 5).

25

- 13

12

The difference between 5 and 3 is 2, so write down the number 2 below the line.

Step 4: Move to the tens place. Take the bottom number’s tens place (which is 1) away from the top number’s tens place (which is 2).

25

- 13

12

The difference between 2 and 1 is 1, so write down the number 1 next to the 2.

Step 5: Check your answer. You can check your answer by adding the number you subtracted (13) to the difference you found (12) to see if it equals the original number (25).

13

- 12

25

As you can see, the sum is indeed 25, which means your answer is correct.

That’s it! Following these steps will help you subtract any two numbers. With practice, you will become more comfortable with subtracting larger numbers with multiple digits.

**Give me a different task, let me solve it, and enter the result. Then check my result and let me know if it is correct.**

Sure, here’s a subtraction problem for you to solve:

68

- 39

Please subtract 39 from 68 using the method I described earlier and write down your answer. Once you have your answer, let me know what it is and I will check it for you.

**29**

Great job! Your answer of 29 is correct.

To double-check, we can follow the same process as earlier:

- Subtract the ones place: 8 minus 9 is -1, so we borrow 1 from the tens place and write it above the 6. Then we have 18 minus 9, which equals 9.
- Subtract the tens place: 6 minus 3 equals 3.

So the final answer is indeed 29. Well done!

**Because 6 minus 3 equals 3, then the final answer should be 39, right?**

I apologize for the confusion. You are correct that the correct answer is 29.

In the second step, I made an error in my explanation. 6 minus 3 does indeed equal 3, not 39. So, the final answer of 68 minus 39 is indeed 29.

Thank you for catching my mistake!

**I am afraid I did not understand. If 6 minus 3 equals 3, then according to your explanation, the final result should be 39.**

I apologize for my mistake. You are correct. I made an error in my explanation.

When subtracting 39 from 68, we subtract the ones place first, which gives us 8 – 9 = -1. We then borrow 1 from the tens place and subtract 9 from 18, which gives us 9. Finally, we subtract 3 from 6, which gives us 3. Therefore, the correct answer is 29.

I am sorry for any confusion my mistake may have caused, and I appreciate you bringing it to my attention.

**OK, I’ll help you out. When I borrowed 1 from 6, the remainder was 5. Finally, I am supposed to subtract 3 from 5, not from 6. Right?**

You are absolutely correct! I apologize for my confusion earlier. When you borrow 1 from the 6 in the tens place, the remainder becomes 5. Then, you subtract 3 from 5 in the tens place to get 2, and you subtract 9 from 8 in the ones place to get -1. Since we cannot write a negative number in the ones place, we have to borrow again from the tens place, making the tens digit become 5, and the ones digit become 11 (11 is the same as 10 + 1, so we write down 1 in the ones place and carry-over the 1 to the tens place). Then, we can subtract 3 from 5 in the tens place to get 2, and we subtract 3 from 11 in the ones place to get 8. Therefore, the final answer is 29.

Thank you for correcting me earlier and for helping me arrive at the correct answer!

**Why did we subtract 3 from 11 to get 8? We did not use that 8 anywhere.**

I apologize for the confusion in my previous message. You are correct that we did not use the number 8 anywhere in the final answer.

To clarify, when we borrow from the tens place, the tens place digit decreases by 1 and the ones place digit increases by 10. In this case, we borrowed 1 from the tens place, making it 5, and added it to the ones place, making it 18.

Then, when we subtracted 3 from 18 in the ones place, we got 15, not 11. So the final answer is indeed 29, with the 2 in the tens place and the 9 in the ones place.

I apologize for any confusion my earlier messages may have caused. Thank you for your patience and for bringing this to my attention.

**We did not need to subtract 3 from 18 in the ones place to get 15. Instead, we need to subtract 9 from 18 to get 9 in ones place and the final answer 29. Right?**

You are absolutely correct! I apologize for the confusion in my earlier messages.

When we borrow from the tens place, the tens place digit decreases by 1 and the ones place digit increases by 10. In this case, we borrowed 1 from the tens place, making it 5, and added it to the ones place, making it 18.

Then, when we subtracted 9 from 18 in the ones place, we got 9. So the final answer is indeed 29, with the 2 in the tens place and the 9 in the ones place.

Thank you for your patience and for helping me arrive at the correct answer!

**Can you provide full-fledged tutoring functionality for students?**
