Countdown arithmetic training pool
Arithmetic puzzles of the Countdown kind: a handful of source numbers, a target, and the job of
writing an expression over the four operations that reaches the target, using each source number
at most once and not having to use them all. A set generated for this pool and three public
datasets read at the pinned revisions named below, laid out twice. Train on either layer or on
both.

SagheerLab/Arithmetic-Reasoning
A high-quality synthetic arithmetic and elementary mathematics reasoning dataset for training and evaluating small language models - not an "ultimate math" claim, but a clean, verified, tiered reasoning dataset where every answer is programmatically checked.
This dataset was built to train 100M-ish models that benefit disproportionately from clean, unambiguous examples. At 50M examples (45M train / 2.5M val / 2.5M test, ~5GB parquet) it is… See the full description on the dataset page: https://huggingface.co/datasets/SagheerLab/Arithmetic-Reasoning.arithmetic-sorl-data
Arithmetic SoRL Data
Training and evaluation data for the SoRL Arithmetic Interpretability Study.
Small transformers trained on integer addition/subtraction, with
SoRL to externalize carry/borrow circuits
as explicit abstraction tokens.

Paper: arXiv:2402.02619 — see Table 8 for complexity classification and Section 3 for sub-task definitions.

Basic Arithmetic
Difficulty-balanced arithmetic dataset (addition, subtraction, multiplication,
division) for evaluating and fine-tuning language models. Problems are classified
into four difficulty tiers (easy, medium_easy, medium_hard, hard) based on
Qwen2.5-0.5B-Instruct performance. Includes 10k training samples, 200
validation, and 400 test (in-domain + out-of-domain phrasings).

Splits are prompt-disjoint — no expression appears in more than one split,
and commutative swaps and trace keys are de-duplicated across splits to prevent
split leakage.

Operands lie in [−999, 999]. Division answers use a fixed DDD.ddd form
(round-half-up to three decimals); division by zero is an atomic <nan>.… See the full description on the dataset page: https://huggingface.co/datasets/vmal/3-digit-arithmetic-scratchpad-traces.Arithmetic
Recursive Arithmetic Transformer training frames
There was no static training file. The model sampled integers online every
step. This dataset replays that sampler with the same Python RNGs used in
train_recursive:

seed = 42 for every run. Each train() call resets both RNGs, so later
finetunes are not a continuation of earlier streams.… See the full description on the dataset page: https://huggingface.co/datasets/Amartya77/Arithmetic.
