Break down the verbal expression into individual parts that can be represented algebraically.
2(x-11)
Practice makes perfect
Let's start forming our algebraic expression by looking at the word "twice." This tells us that we should multiply 2 with something.
2*
The part that comes after this informs us of what we should be multiplying by 2. The words "the difference of ... and ..." indicate that we should subtract two things.
... - ...
The two terms that we are subtracting are: "a number" and "11." Since "a number" comes first in the verbal expression, it should be on the left-hand side of the addition.
a number - 11
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.
twice the difference of& a number and 11
2 * ( x -& 11 )
Note that this is only one of multiple ways to algebraically express the given verbal expression.
