# SUBTRACT Function

Returns the value of subtracting the second argument from the first argument. Equivalent to the - operator.
• Each argument can be a literal Integer or Decimal number, a function returning a number, or a reference to a column containing numeric values.

NOTE: Within an expression, you might choose to use the corresponding operator, instead of this function. For more information, see Numeric Operators.

Wrangle vs. SQL: This function is part of Wrangle, a proprietary data transformation language. Wrangle is not SQL. For more information, see Wrangle Language.
