Digest the problem statement a few words at a time until the figures/tables you've prepared would allow someone who had never seen the problem statement to understand the problem.
Your equation(s)/inequalities must come from sanctioned documentation(e.g. textbook, formula sheet, notes). Do NOT start with equations that were derived for special-case examples.
Use proportional reasoning, investigation of functional relationships, substitution, algebraic manipulation, and other deductive methods to work toward inferences.
For algebraic/numeric results, clearly box a complete response including appropriate sign, labeling variable (don't just box an expression, box a relationship with at least a left side and a right side), and units.
