How to Use Perplexity for Math? + Example Prompts

In this tutorial, we will explore how to use Perplexity for math. You can check if it is actually precise and show you how to upload PDFs to get math homework help.

This is useful to you because let’s be honest — Maths is hard.

Whether you are stuck on a tricky algebra equation or trying to understand a confusing calculus concept, a standard calculator often isn’t enough. You don’t just need the answer; you need to understand how to get there.

Enter Perplexity AI.

While most people use Perplexity for searching the web, it is also a powerful Perplexity AI math solver. Unlike a basic calculator, it can read word problems and explain formulas. It can even look at a photo of your homework to help you solve it.

What is Perplexity in Math?

Before we start typing numbers, let’s clear up a common confusion. When people search for “What is Perplexity in math?”, they usually mean one of two things:

The AI Tool: Using the Perplexity app to solve math problems (which is what this guide is about).

The Statistics Metric: In probability and information theory, “perplexity” is a measurement of how well a probability model predicts a sample. (Don’t worry, we won’t be doing statistics today!)

For students and learners, Perplexity is a reasoning engine.

It doesn’t just give you a number. It reads your problem, breaks it down into steps, and teaches you the logic.

Step 1: Solving Basic Math Problems

The easiest way to use Perplexity is as a smart conversational calculator.

How to do it:

Open Perplexity (Web or App).
Type your question in natural language.

Example: “What is the square root of 144 plus 15% of 500?”
Example: “Solve for x: 3x + 12 = 4x – 5”

Review the Steps: Perplexity won’t just say “x = 17”. It will show you the subtraction and division steps it took to get there.

1. Step-by-Step Problem Solving (Algebra)A screenshot of Perplexity AI solving the equation 3x + 12 = 4x - 5. The "Answer" section breaks down the solution into clear steps:Step 1: Subtract 3x from both sides (12 = x - 5).Step 2: Add 5 to both sides (17 = x).Verification: It substitutes x = 17 back into the original equation to prove equality (63 = 63).

Why is Perplexity good for math here?

It understands “wordy” math. You can type “I have 5 apples and buy 3 more, then give half to my friend” and it will convert those words into a math equation.

Step 2: Use ‘Chain of Thought’ Prompts

You don’t need a paid subscription to get the AI to think deeply. You just need to ask it to “show its work.”

In the standard free mode, if you ask a hard question, the AI might guess quickly. But if you use a Chain of Thought (CoT) prompt, you force it to slow down and act like a reasoning engine.

How to do it:

Don’t just ask: “What is the derivative of x^3 * ln(x)?”
Instead, add this magic phrase: “…Solve this step-by-step and explain each logical rule you use.”
For Word Problems: “Break this problem down into 3 logical parts before answering. Let’s think step-by-step.”

A screenshot showing Perplexity explaining how to find the derivative of x^3 * ln(x). The answer:Identifies the components for the Product Rule (u = x^3, v = ln(x) ).Applies the formula $(uv)' = u'v + uv'.Simplifies the result step-by-step to the final answer: x^2(3 ln(x) + 1).

Why this works for free:

By asking for the “steps,” you stop the AI from hallucinating a random number. It effectively mimics the expensive “Reasoning” models by forcing the standard model to verify its own logic as it writes.

Step 3: How to Use Perplexity for Math PDF (Homework Help)

This is the best feature for students. If you have a homework worksheet saved as a PDF, you don’t need to type out every question.

How to upload a PDF in Perplexity:

Look for the “+” (Plus) icon or “Attach” button in the search bar.

A screenshot showing the search bar at the bottom of a thread with the text "Ask a follow-up." A red arrow points to the attachment icon (paperclip), indicating that users can add more context or new files even in the middle of a math problem-solving session.

2. Select your math worksheet PDF from your computer or phone.

A screenshot of the actual PDF worksheet page 4-5. It shows "Q.7" which reads: "₹2450 were divided among 65 children... each girl gets ₹50 and each boy gets ₹30 then find the number of girls." This provides the source material for the AI's subsequent answer.

Type your prompt: “Solve problem Q. 7 on page 5 and explain the Perplexity AI math formulas used.”

A screenshot showing the file upload feature. The user has uploaded a file named "Maths worksheet.pdf" and prompts the AI: "Solve problem Q.7 on page 5 and explain the Perplexity AI math formulas used." This demonstrates how users can get help with specific homework questions from a document.

4. Analyze: Perplexity will read the document, find problem 7, and solve it.

A screenshot of Perplexity's response to the uploaded PDF question. It sets up two equations based on the text:Total children: g + b = 65 Total money: 50g + 30b = 2450 It then begins solving using the Substitution Method, expressing b as 65 - g.

A screenshot continuing the solution. It solves for g (girls) getting 25 and b (boy) getting 40. Crucially, it includes a section titled "Perplexity AI Math Formulas Used" which shows the actual Python code (using the sympy library) it ran to calculate the answer, ensuring accuracy over mere text prediction.

Pro Tip: You can also upload an image. Take a photo of your textbook problem, upload it, and ask “How do I solve this?”

Step 4: Creating Study Guides and Formulas

Perplexity isn’t just a solver; it’s a tutor. You can use it to memorize formulas.

Try these prompts:

1. “Create a cheat sheet for all the geometry formulas I need for 10th grade.”

A screenshot of a request to "Create a cheat sheet for all the geometry formulas I need for 10th grade." The AI lists key formulas like Distance Formula, Section Formula, Area of Triangle, and Pythagoras Theorem, providing a quick study guide.

2. “Explain the Quadratic Formula to me like I am 12 years old.”

A screenshot of a conceptual question: "Explain the Quadratic Formula to me like I am 12 years old." The AI explains it as a "magic recipe to find where a curvy hill... touches the ground." It breaks down the formula $x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$

3. “Give me 5 practice problems for linear algebra with answers.”

A screenshot of a request for "5 practice problems for linear algebra with answers." The AI provides formatted math problems covering systems of equations ("Solve the system"), determinants ("Compute the determinant"), and singular matrix checks, effectively acting as a tutor or quiz generator.

This makes Perplexity AI math free capabilities a great alternative to hiring a private tutor.

Step 5: The ‘Infinite Quiz’ Mode (Practice for Exams)

One of the best free features is that Perplexity doesn’t just solve the problem. It can generate new ones for you to practice. This is something a normal calculator can’t do.

How to do it:

1. After Perplexity solves your homework question (e.g., a quadratic equation), don’t close the tab.

2. Type this prompt: “That made sense. Now give me 3 similar problems to practice with, but don’t show the answers yet.”

Screenshots shows an interactive learning session.

The Request: The user asks for "3 similar problems to practice with, but don't show the answers yet," testing their understanding.

The Feedback: After the user submits their answers ("1. The solution is x=5...", "3. Av=5/11"), the AI grades them. It confirms "Great job on Problem 1!" and "Problem 2... is correct," but points out that "Problem 3: 5/11 is incorrect" and provides the correct vector calculation explanation.

3. Solve them on paper.

4. Check your work: Type “Okay, here are my answers: 1) x=4, 2) x=9… Did I get them right?”

A screenshot of Perplexity AI grading a user's math practice answers. The user submits solutions for three problems (system of equations, determinant, and matrix-vector product). The AI responds with specific feedback: it confirms "Great job on Problem 1!" and validates the determinant in Problem 2. It marks the answer for Problem 3 as incorrect ("5/11"), provides the correct matrix-vector multiplication steps to reach the vector result (5/11), and assigns a final score of "2/3".

Why use this?

Unlimited Practice: You basically have an infinite textbook.
Active Recall: It forces you to actually learn the method, not just copy the answer.
Zero Cost: It uses the standard text model, so it never hits the “Pro” limit.
