A result the Edexcel formulae booklet prints is marked as such; one it does not print is marked to learn; and a result badged derived in the lesson is a working line the notes build in front of you rather than a standard result to memorise.

3x+2y≤20 becomes 3x+2y+s1=203x + 2y \le 20 \text{ becomes } 3x + 2y + s_{1} = 20NOT IN THE BOOKLET: DERIVED IN THE LESSONConditionsSlack variable s₁ ≥ 0, added to a ≤ constraint. A ≥ constraint takes a subtracted surplus variable and then an artificial variable as well.

Every formula in the library is indexed by unit on the equation index, and the Decision Mathematics 1 notes are where this result is derived and used.
