Linear Programming by the Simplex Method Study Guide: NEB 12 Maths

Seven-session plan

Turn Linear Programming by the Simplex Method into retrievable knowledge

Linear programming optimizes a linear objective under linear constraints. The simplex method moves among feasible corner solutions using pivots while tracking slack variables and optimality conditions.

1. Map prerequisites and definitions.
2. Derive or justify the main relation: Convert inequalities to standard form with slack/surplus variables, build a tableau, choose entering and leaving variables by the stated convention, pivot, and repeat until optimal.
3. Redraw diagrams from memory.
4. Study this worked checkpoint: A small production model maximizes profit subject to labor and material limits; slack variables measure unused resources at a feasible solution.
5. Mix conceptual and numerical questions.
6. Complete a timed closed-book set.
7. Retest only the first wrong decision in each answer.

Use contrast tables and error cards

Place easily confused ideas side by side. Write what stays fixed, what changes, the governing equation and the observable consequence. One high-value warning is: Ignoring non-negativity, pivoting on a nonpositive ratio, mixing maximization conventions, or reporting an infeasible tableau as optimal.

Use spaced retrieval: ten minutes today, a closed-book test tomorrow and a mixed review after one week. Explain every graph or diagram aloud before using algebra.

NEB answer method

Model → evidence → equation → check

First identify the system and what the question asks. Label the diagram, apparatus or reaction with SI quantities, then state the principle before selecting an equation. Solve symbolically where possible and check units, limiting cases and chemical or physical meaning.

Make the idea concrete in Nepal

Connect the model to a school laboratory, household technology, health, environment, energy or local material. The example should clarify the science rather than merely mention a place. Compare a prediction with an observation and record uncertainty.
