Exercise 1 Page 67

The key phrase is "...more than..." This indicates that we should add two things.

\dots + \dots

The two terms that we are adding together are: "six" and "a number." There are two ways in which we can write it.

6 + a number or a number + 6

Let's choose the first option. 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.

s i x m o r e t h a n a n u m b e r 6 + x

Note that this is only one of multiple ways to algebraically express the given verbal expression.
