Present solutions to multi-step problems in the form of valid chains of reasoning, using symbols such as equals signs appropriately (for
example, rubrics award less than full credit for the presence of nonsense statements such as 1+4=5+7=12, even if the final answer is correct),
or identify or describe errors in solutions to multi-step problems and present corrected solutions.
