Numerithm: Math & Coding

Numerithm brings number theory and beginner programming together in one guided learning app. Learn ideas in small steps, run Dart code, and solve challenges with exact numerical answers.

LEARN DART THROUGH NUMBERS

Start with approachable lessons on values, variables, conditions, loops, totals, and functions. Then use those skills to explore factors, primes, multiples, common factors, number patterns, remainders, cycles, and other useful ideas.

WRITE AND RUN REAL CODE

Use the built-in Dart workspace to try an idea, print intermediate values, and calculate an answer. Starter code helps you begin without forcing one solution. Programs run locally with time limits and cannot access your files or the internet.

SEE CODE ONE STEP AT A TIME

Use the step-by-step view to follow each instruction and watch variable values change. This makes loops, conditions, and calculations easier to understand.

SOLVE NUMBER CHALLENGES

Each challenge explains the mathematical idea, gives a clear numerical goal, and offers hints when needed. Enter one number to check your answer, or use code to explore a larger search.
