In Lesson Manual 3.2, words in a mathematical context are discussed. At times, it is not entirely clear whether the word is part of the equation. For instance, in the equation 2.5+2.5 = 5 pounds, is pounds part of the equation? The word does not need to be there to make the equation true but in context it seems as if it is part of the equation.
We’ve been going back and forth on this and can kind of see either way, but wanted to see your suggestion since we couldn’t find a specific example.
Thank you for your help!
