Terms in a Mathematical Expression

Click For Summary

Discussion Overview

The discussion revolves around the definition and interpretation of "terms" in mathematical expressions, specifically in the context of an equation. Participants explore the nuances of what constitutes a term, including its syntactical name, its value, and its arguments within mathematical operations.

Discussion Character

  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions whether "ab" refers to its syntactical name, its value, or the arguments (a, b) in the multiplication function.
  • Another participant suggests that the reference might be to the ordered triplet in the addition function instead.
  • A different viewpoint emphasizes that the interpretation of terms depends on context and is not governed by a general rule, suggesting that language interpretation plays a significant role.
  • One participant states that in high school algebra, a term is defined as an expression being added to another, identifying "ab," "bc," and "cd" as the three terms in the provided example.
  • Another participant argues that the term "term" is not a formal mathematical object and can refer to any of the three interpretations mentioned, asserting that the value and argument are effectively the same in practice.

Areas of Agreement / Disagreement

Participants express differing views on the definition of a term, with no consensus reached on a singular interpretation. The discussion remains unresolved regarding the precise meaning of "term" in mathematical contexts.

Contextual Notes

The discussion highlights the ambiguity in the terminology used in mathematics and the dependence on context for interpretation. There are unresolved questions about the implications of each interpretation on mathematical understanding.

When we refer to terms in an equation, what EXACTLY are we referring to? Suppose for example we have:

ab + bc + cd = A

Suppose somebody refers to term "ab". Are they referring to the syntactical NAME "ab", the IMAGE of ab (i.e., it's value), or the ARGUMENT (a,b) which belongs to some ordered triplet in the multiplication function?

Do you mean the ordered triplet in the addition function? Yes, I believe that's it.

I don't think there is any general rule for this. It depends on the context. It's a matter of interpreting English unless you are studying a text that is using such terminology to describe the precise syntax of a symbolic language.

For example, one might just as well ask "Who is the 'we' that you refer to?" or "EXACTLY what particular passages of text are you talking about?".
 
In high school algebra II, we're taught that a term is an expression that is being added to another. In your example, you would have three terms: ab, bc, and cd.
 
A "term" is not a formal mathematical object, it's just a word that's used for conveying a point. It can mean any of the three things you mentioned, and it's still (mathematically) unambiguous, because two of the three are the same (the value and the argument to the operation, since the value is what is actually being used as an argument) and the other one (the name) has no bearing on the mathematical value of the sentence.
