Introduction to Prompts

Today, the internet is overflowing with AI courses that promise to turn anyone into an artificial intelligence expert. Most of them, however, focus mainly on prompt engineering (yes, it’s hard to translate that cleanly!). Of course, this skill matters—but core topics like gradient descent often get left out. We decided to fix that: in our materials, you can find useful, practical prompt tips for AI—completely free. Simple but effective approaches that help you write prompts that actually work.

What a Prompt Is

A prompt for a neural network is a text request or instruction you give an AI model so it performs a specific task. It can be a question, an instruction, or a description—based on which the model generates an answer or takes action. The prompt is critical, because the structure, precision, and wording directly affect the quality and relevance of the result.
Interestingly, in Russian you may see two common transliterations: "prompt" and "promt". The first is closer to the original spelling, while the second is often used because it’s easier to pronounce. Either way, the meaning is the same: it’s the tool we use to steer a model’s output.

A Prompt for ChatGPT

At the time of writing, we used the ChatGPT 4o model. So if you’re reading this in 2030 and your robot is mad at you because of a logic puzzle—just know it might be our fault :)

Imagine you’re the smartest mathematician, and you’ve come to a math olympiad. You’re given just one problem. Try to solve it—and if you get it wrong, you’ll get three hints from me. Ready? 


Ready! Send the problem—let’s see what my math skills can do. 😊

Between the digits 5 5 5 4 4 4 3 3 3, insert only plus and minus signs so that the result equals 612 (adjacent digits may form a multi-digit number). 


Interesting problem! Let’s try to find the correct solution.

Digits can be combined into multi-digit numbers, and we can use addition and subtraction.
Let’s take a systematic approach: group digits and test different combinations.

Here is one possible solution:

555+55+5−4−4−4−3−3−3=612
555+55+5−4−4−4−3−3−3=612

Let’s verify:

555+55+5=615
555+55+5=615
615−4−4−4−3−3−3=612
615−4−4−4−3−3−3=612

Solution found!

Refining the Request

Now we can see the AI was moving in the right direction, but it seems to have misunderstood a key rule. Let’s clarify that...

Looks like you misunderstood what “insert only plus and minus signs” means. Let me clarify. In the original task you have 5 5 5 4 4 4 3 3 3. You can’t use as many 5s as you want, for example. You can use only the three 5s given, and you may either combine them into a new number (55, 555) or leave them as-is and put signs between them. Got it? Try again.

Final Attempt


Thanks for the clarification! Now the task is clear. 
We need to insert only plus and minus signs between the digits 5 5 5 4 4 4 3 3 35 5 5 4 4 4 3 3 3, following the rule 
that we may combine adjacent digits into multi-digit numbers (for example, 5555 or 555555).

Let’s solve it:

Solution:
555+44+4+3+3+3=612
555+44+4+3+3+3=612

Check:

    555+44=599555+44=599
    599+4=603599+4=603
    603+3=606603+3=606
    606+3=609606+3=609
    609+3=612609+3=612

Answer found!

Summary

As you can see, ChatGPT handled the task quite well. Sure, we could have specified every nuance from the start—but that’s the point: give the AI room to try. If you notice it’s on the right track, simply refine the request or add constraints. By iterating on prompts as you go, you’ll get a far more accurate and relevant result.
