+The dataset is a collection of simple math word problems focused on arithmetics. It is derived from <https://huggingface.co/datasets/omarxadel/MaWPS-ar>.
 
 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 of the mathematical problem (a number)
+- 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 out-source the computations in the reasoning chain to a calculator.

 ## Attributes:
 
+- `id`: id of the example
 - `question`: problem description in English
 - `question_arabic`: problem description in Arabic
 - `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
-- `equation`: equation that needs to be solved for `x` to obtain the result. Usually in a form of "x = ..." but not always.
+- `equation`: an equation that needs to be solved for `x` to obtain the result. Usually in the form of "x = ..." but not always.
 - `expression`: arithmetic expression derived from `equation` that solves it for `x`
 
 
-## Content and data splits
+## Data splits
+
+We provide 2 variants of the dataset. In the first one, the data splits correspond to the original one and can be loaded using:
+
+```python3
+datasets.load_dataset("MU-NLPC/calc-mawps", "original-splits")
+```
+
+The second one is filtered to prevent data leaks (overly similar examples in train and test/val splits) in between and across datasets in [Calc-X collection](https://huggingface.co/collections/MU-NLPC/calc-x-652fee9a6b838fd820055483).
+Specifically, we filtered out around 2,500 near-duplicates from the train set that were similar to some instances in the MAWPS val and test splits and ASDiv-A test split. You can load this variant via:
+
+```python3
+datasets.load_dataset("MU-NLPC/calc-mawps")
+```
 
-Both are consistent with the original source dataset.
