How do you write the algebraic expression: the sum of 11 and k?

Oct 21, 2017

$11 + k$

Explanation:

Well, an expression in mathematics is defined as a phrase containing numbers, variables and operators (add, subtract, etc). This differs from an equation, in which the "equals" sign is present, indicating that two (or more) things are equal to something.

So, $k$ is a variable and $11$ is a number, and the "sum" of something essentially means to add these factors. Therefore, the sum of 11 and $k$ means to add them together. Thus,

The sum of 11 and $k$:

$11 + k$
