## A-level Mathematics/Edexcel/Decision 2Edit

Decision Mathematics 2 is an applied mathematics module for the Edexcel Examination Board, which builds upon the foundations of Decision Maths that were studied in the 'D1' module.

**Note**: *This book is so you can gain an alternative explanation for the concepts described and it should NOT replace your D2 textbook!*
