About These 9th Class Math Notes
These notes follow the new Class 9 Mathematics book taught in Punjab from 2026-27. The same book is used by every BISE Punjab board: Lahore, Gujranwala, Multan, Rawalpindi, Faisalabad, Sargodha, DG Khan, Bahawalpur and Sahiwal. Every solution shows the full working, not just the final answer, so you can check each step of your homework.
Try each question yourself first, then open the solution to find where your method went wrong. Attempt the review exercise last, without help, as a test of the whole unit.
