Question

how many terms are in this expression?
k + n - 1

Explanation:

Step1: Define a term

In an algebraic expression, a term is a single number, variable, or the product of numbers and variables, separated by addition or subtraction signs.

Step2: Identify terms in \(k + n - 1\)

• The first term is \(k\) (a variable).
• The second term is \(n\) (a variable).
• The third term is \(-1\) (a constant, which can be thought of as \(-1\) separated by the subtraction from \(n\)).

So, by identifying each part separated by \(+\) or \(-\), we find there are 3 terms.

Answer:
