Calculadora Primaria

Primary Calculator is an app for elementary school children to check their math problems on their own.

🎯 HOW DOES IT WORK?
The child solves the problem in their notebook, enters the answer into the app, and it tells them if it's correct or incorrect. The app never gives the answer—the child has to find it themselves.

✏️ AVAILABLE OPERATIONS
- Addition—with multiple addends
- Subtraction
- Multiplication
- Division with quotient and remainder

📐 JUST LIKE IN THE NOTEBOOK
The numbers are displayed aligned in columns, just like in a school notebook: units with units, tens with tens. The child instantly recognizes the format because it's exactly the same as in class.

✅ GREEN OR RED
- Green = Correct! Very good.

- Red = Incorrect, try again.

No hints, no solutions. Confirmation only if the result is correct or not.

🔢 ON-SCREEN NUMERIC KEYPAD
Large, easy-to-use keypad, designed for small fingers.

👨‍👩‍👧 FOR PARENTS AND TEACHERS
No ads, no in-app purchases, no registration. A clean and straightforward tool that fosters independence and self-correction in math.

Ideal for children ages 6 to 12.
