Arith Algorithm

Arithmetic Algorithms Lab is an educational app designed to help students, parents and learners understand how arithmetic algorithms work through clear step-by-step demonstrations.

Instead of only showing the final answer, the app breaks each calculation into small visual stages so users can follow the logic behind the method. It is suitable for classroom revision, home learning, self-study and anyone who wants to strengthen their understanding of core arithmetic.

Main features:

• Step-by-step arithmetic simulations
• Clear explanations for each calculation stage
• Worked examples for column addition, column subtraction, long multiplication, long division and Euclidean GCD
• Adjustable simulation speed
• Manual step controls and auto-play mode
• Colourful visual cards and learning panels
• Settings tab for theme, display and learning preferences
• Local app activity logs for learning review
• iCloud Key-Value Store option for simple settings backup where available

Included arithmetic topics:

• Column Addition
• Column Subtraction
• Long Multiplication
• Long Division
• Euclidean Algorithm for Greatest Common Divisor

Arithmetic Algorithms Lab is built to make maths easier to understand by showing how each method is achieved, one step at a time.

Whether you are revising basic arithmetic, supporting a child’s learning, or creating classroom demonstrations, this app provides a simple and visual way to explore calculation methods.

No account is required. The app works offline for its core learning features.
