Drawing equations effectively is key to getting accurate results from AI Math Notes. Follow these guidelines to improve recognition accuracy.

​
Basic Drawing Technique

The application uses your mouse movements to create white lines on a black canvas:
Each stroke you draw has these characteristics:
  • Width: 5 pixels
  • Color: White (#FFFFFF)
  • Smoothness: Lines are created continuously as you drag the mouse
self.canvas.create_line((self.last_x, self.last_y, x, y), fill='white', width=5)

​
The Equals Sign Rule

The most important rule for using AI Math Notes effectively:
The equals sign must be the last thing you draw before clicking Calculate.
The AI looks for an equals sign with nothing to the right of it to determine where to place the answer. Here’s how it works: 
def draw_answer(self, answer):
    # Find the position of the last equals sign drawn
    if not self.actions:
        return
    
    last_action = self.actions[-1]
    last_coords = last_action[-1][-1]
    equals_x = last_coords[2]
    equals_y = last_coords[3]
    
    # Set the position to draw the answer
    x_start = equals_x + 70
    y_start = equals_y - 20
The answer will be positioned 70 pixels to the right and 20 pixels above the endpoint of your last stroke.

Best Practices

​
Draw Clear Numbers

Make your numbers and symbols distinct and well-spaced for better recognition by the GPT-4o vision model.
The AI uses computer vision to interpret your handwriting, so clarity matters:
  • Write numbers large enough to be clearly recognized
  • Leave space between different elements of the equation
  • Keep consistent sizing across the equation

​
Equation Format

Follow this sequence for best results:
  1. Draw the left side of the equation (e.g., 5 + 3)
  2. Draw the equals sign (=) last
  3. Leave the right side empty
  4. Click Calculate or press Enter
5 + 3 =
✓ Equals sign is last, right side is empty

​
AI Instructions

The application sends specific instructions to GPT-4o: 
{"type": "text", "text": "Give the answer to this math equation. Only respond with the answer. Only respond with numbers. NEVER Words. Only answer unanswered expressions. Look for equal sign with nothing on the right of it. If it has an answer already. DO NOT ANSWER it."}
The AI is instructed to:
  • Only provide numerical answers
  • Only solve equations with empty right sides
  • Ignore equations that already have answers

​
Supported Operations

Since the application uses GPT-4o’s vision capabilities, it can recognize:
  • Basic arithmetic: +, -, ×, ÷
  • Fractions and mixed numbers
  • Exponents and roots
  • More complex mathematical expressions
The AI model (GPT-4o) is quite sophisticated and can handle a wide variety of mathematical notation. Don’t be afraid to try complex equations!

​
Troubleshooting Recognition

If the AI isn’t providing accurate results:
  1. Check your equals sign: Make sure it was the last thing you drew
  2. Improve clarity: Use Undo to redraw unclear symbols
  3. Use Clear: Start fresh if the equation is messy
  4. Space it out: Give more room between numbers and operators
Remember, you can always use Cmd/Ctrl Z to undo the last stroke without clearing the entire canvas.
