+It pairs symbolic math expressions using basic operators (combining integers with the operators `+`, `-`, `/`, `*`) and parentheses for grouping, with symbolic DSL function calls compatible with the module **DIA intent sequencer** format. Function and parameter names are randomized to help reduce memorization, encouraging structural reasoning. Numbers in the symbolic expressions are randomized integers between -99999 and 99999, sampled to cover and balance different number lengths (1-digit to 5-digit numbers).
 
 The dataset was programmatically generated using [`calculator_synthetic_data_generator.py`](https://github.com/gh9869827/fifo-dev-dsl/blob/main/fifo_dev_dsl/dia/demo/calculator_synthetic_data_generator.py), which builds symbolic expressions and randomized tool mappings.
