Description

Entering a value such as x1-x0 into a math expression node is causing a compiler error in blueprints.

This is inconsistent with the behavior in 4.12.5, when entering the same expression would cause no error. This is a regression.

Steps to Reproduce
  1. Open the editor
  2. Create a new actor blueprint
  3. Right-click and search for Add Math Expression
  4. When the node appears, type in x0
  5. Compile

Result: Error message appears along the lines of:

Error PARSE ERROR in ' K2Node_MathExpression_29 ': Unhandled trailing '1-x0' at the end of the expression

Expected: Behavior would be consistent with 4.12.5 and no error would appear.
