Documenting Visual Math Procedures for Inventory Tracking

In a logistics training simulation, your team uses color-coded tokens to visualize ledger adjustments. Red tokens represent backordered items (negative values). You are tasked with explaining to a new hire how to use these tokens to solve the subtraction problem 5(3)-5 - (-3) using the 'take-away' method.

Describe the exact steps for this procedure. In your response, specify how many tokens of which color you begin with, the specific action you take to represent the subtraction of the second value, and what the final result looks like in terms of token count and color.
