# Math Formulas QA

Deterministic synthetic math QA dataset generated with seed `1337`.

## Properties

- 2,000,000 unique rows
- 1,800,000 train
- 100,000 validation
- 100,000 test
- 100,000 rows per Parquet shard
- Every row is validated before it is written
- `kind` alternates between `problem` and `solution`

## Columns

- `question`
- `answer`
- `text`
- `question_tex`
- `answer_tex`
- `family`
- `difficulty`
- `kind`
- `validated`
- `validator`
- `formula_hash64`

## Families

Arithmetic, fractions, equations, inequalities, absolute values, powers, roots,
quadratics, binomial expansion, combinations, permutations, factorial ratios,
series, telescoping sums, probability, geometry, modular arithmetic, systems of equations,
and proportions.

## Validation

Combinatorics and factorial-based rows use `scipy.special.comb(..., exact=True)` and
`scipy.special.factorial(..., exact=True)` when SciPy is available. The rest are checked
with exact integer and rational arithmetic.
