The discussion revolves around a mathematical age puzzle involving Holly and Ivy, which is noted for its confusing wording. Participants express frustration over the lack of clear age definitions and the challenge of setting up the correct equations. There is a consensus that the problem presents contradictory information, leading to misinterpretations and confusion about the reference year for the ages. Ultimately, through algebraic manipulation, some participants arrive at the conclusion that the answer to "How many years ago was that?" is 6 years ago. The conversation highlights the importance of clarity in problem statements and the potential for miscommunication in mathematical contexts.
