Exercise 4 Page 7

We are asked to write an algebraic expression for the given verbal expression. The key phrase in the verbal expression is the sum of $\dots$and$\dots$ This indicates that we should $\text{add}$ two things. The two terms that we are adding together are $\text{a}$ $\text{number}$ and $14.$ Since $\text{a}$ $\text{number}$ comes first in the verbal expression, it should be on the left-hand side of the addition. When we say a number, this is indicating an arbitrary number or a variable. If we call this number $x,$ we can complete our expression. Note that this is only one of multiple ways to algebraically express the given verbal expression.
