.. _auto_math_subtract:

*SUBTRACT BETWEEN TWO VALUES*
=============================

Subtracts Value 2 from Value 1 and returns the scalar result (Value 1 − Value 2). Use this worker whenever a simple numeric difference is needed inside a workflow transformation chain.

     - ✓
     - The minuend — the scalar number from which Value 2 will be subtracted; must be a numeric value (no default, required).
