M.2-Algebra, models, units and dimensional consistency

Change the subject of equations, solve simple and simultaneous equations, use the quadratic formula, substitute quantities with consistent units, check dimensional consistency, use percentages and interpret mathematical symbols.

Use m.2-algebra, models, units and dimensional consistency to connect the rule to the data and decision in the question.

This matters because m.2-algebra, models, units and dimensional consistency determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply m.2-algebra, models, units and dimensional consistency to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: M.2-Algebra, models, units and dimensional consistency is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
