 # Dataset Card for "Calc-asdiv_a"
 
-TBD
 
-[More Information needed](https://github.com/huggingface/datasets/blob/main/CONTRIBUTING.md#how-to-contribute-to-the-dataset-cards)
+## Summary
+
+The dataset is a collection of simple math word problems focused on arithmetics. It is derived from the arithmetic subset of ASDiv ([original repo](https://github.com/chaochun/nlu-asdiv-dataset)).
+
+The main addition in this dataset variant is the `chain` column. It was created by converting the solution to a simple html-like language that can be easily
+parsed (e.g. by BeautifulSoup). The data contains 3 types of tags:
+
+- gadget: A tag whose content is intended to be evaluated by calling an external tool (sympy-based calculator in this case)
+- output: An output of the external tool
+- result: The final answer to the mathematical problem (a number)
+
+
+## Supported Tasks
+
+This variant of the dataset is intended for training Chain-of-Thought reasoning models able to use external tools to enhance the factuality of their responses.
+This dataset presents in-context scenarios where models can outsource the computations in the reasoning chain to a calculator.
+
+
+## Attributes:
+
+- `id`: id of the example
+- `question`: problem description in English
+- `chain`: series of simple operations (derived from `expression`) that lead to the solution
+- `result`: the solution for x as a number or fraction (string)
+- `result_float`: same as `result` but converted to a float
+- `result_unit`: the units of the result
+- `grade`: an estimate of the school grade in which the problem would be practiced
+- `source_question`: the source from which the example originates
+
+
+## Data splits
+
+The dataset does not contain data splits. We consider the whole dataset as a testing benchmark.
+
+
+## Licence
+
+CC BY-NC 4.0, consistent with the original source dataset linked above.
+
