About this app

Learn number theory and beginner programming together with Numerithm. Follow friendly lessons, run real Dart code, and solve mathematical challenges with exact numerical answers.

LEARN DART THROUGH NUMBERS

Begin with clear introductions to values, variables, conditions, loops, totals, and functions. Then use those programming skills to explore factors, prime numbers, multiples, common factors, number patterns, remainders, cycles, and other useful number theory ideas.

WRITE AND RUN DART CODE

Use the built-in code editor to test an idea, print intermediate values, and calculate an answer. Helpful starter code gets you moving without forcing one solution. Programs run locally in a restricted environment with a hard time limit and cannot access your files or the internet.

FOLLOW CODE STEP BY STEP

Trace a program one instruction at a time and watch variable values change. Visual code tracing makes loops, conditions, calculations, and algorithms easier to understand.

SOLVE NUMBER CHALLENGES

Each challenge introduces the mathematical idea, gives you a clear numerical goal, and provides hints when you need them. Enter a number to check your answer, or use the Dart workspace to explore a larger search.
