# Going From a Sequence of Operations to an Expression

Need some practice going the other direction? Going from an Expression to a Sequence of Operations

The sequence of operations
‘*
take a number,
multiply by
* $\,2\,,$ *then add* $\,1\,$’
is represented by
the expression
$\,2x + 1\,.$

The sequence of operations
‘*
take a number,
add
* $\,1\,,$
*then multiply by* $\,2\,$’
is represented by
the expression
$\,2(x+1)\,.$

(Of course, a variable other than $\,x\,$ can be used.)
