ARITHMA teaches kids the mental-math shortcuts ancient Indian scholars used 3,000 years ago — the same techniques today's top students use to solve in seconds what calculators take longer to type.
Short video lessons. Daily 5-minute practice. Aligned to 84 Common Core standards. For families learning at home and schools looking for supplemental math curriculum.
An ancient Indian mathematical tradition spanning 3,000+ years — that's faster, more elegant, and more pattern-based than the standard arithmetic taught in American schools today.
Vedic math is a system of mental-math shortcuts drawn from sacred Indian texts written between 800 BCE and 600 CE. These are the same texts that gave the world the concept of zero, negative numbers, the decimal system, and the geometric rule we now call the Pythagorean theorem — discovered in India 300 years before Pythagoras was born.
American schools teach one slow algorithm per operation. Vedic math gives kids 16 pattern-based shortcuts they can pick from depending on the problem. The result is kids who do mental arithmetic faster than calculators — and actually understand why the math works.
ARITHMA teaches all 16 of these techniques through short videos and daily 5-minute practice — for kids in Grades K–12.
Get My Free Lessons →Three steps from sign-up to your first lesson. Built for kids who hate math AND kids who love it.
Create your child's profile in 30 seconds. Pick their grade level — the lessons auto-tune to their Common Core standards.
Choose a learning track (Beginner, Speed Track, Practice Track, or Pattern Track) and step into our online lesson library.
Each mental-math technique IS a new tool. Learn faster math → unlock more battle options. Knowledge becomes literal power.
Read these once. Tomorrow your kid will be doing them at the dinner table.
Take the 2-digit number. Split the digits apart. Add them. Put the sum in the middle.
Take the digit before the 5. Multiply it by the next number up. Stick 25 on the end.
All digits except the last: subtract from 9. Last digit: subtract from 10.

An animated intro to ARITHMA — See why ancient Indian math beats school math every time.
Vedic math has three branches drawn from different ancient Indian sources. Together they cover every math domain in Common Core — at every grade level.
16 mental-math rules drive the mental-math curriculum. Every rule a child masters becomes a permanent new spell — a complement method for fast subtraction, a crosswise method for multiplication, a proportional method for fractions, and 13 more.
The world's oldest geometry rules power geometry lessons. These same texts state the Pythagorean theorem 300 years before Pythagoras was born. Kids rebuild corrupted worlds using authentic geometric proofs from this tradition.
Vedic astronomy and logical inference drive the statistics lessons. Ancient Indian astronomers tracked planetary cycles, built predictive models, and developed probabilistic reasoning — exactly what Common Core Statistics demands.
A solo kid practicing at home. A family that wants to learn together. A school district adopting standards-aligned supplemental curriculum.
Learn the mental-math shortcuts that make you the fastest student in your class.
Screen time that builds real math fluency — with visible weekly progress reports.
K–12 mental-math curriculum with 100% Common Core domain coverage across all grades.
Every standard listed is addressed through at least one specific, repeatable game mechanic with built-in mastery tracking.
